[0058] The spare solar module (10) that can be placed on the base plate (20) of the present embodiment can include at least one member that implements a solar cell function, and its type or shape can be varied.

[0059] For example, a spare solar module (10) may include a combination of multiple solar cells connected in series or parallel via wires.

[0060] As a specific example, the spare solar module (10) may include a module before the solar module is completed. As an example, the spare solar module (10) may include a solar module in which a pre-heating process for preventing distortion of the solar module before the temperature rises and a laminating process for pressing the solar module on a heating plate have been completed.

[0061] The spare solar module (10) can be one of various types, and in addition, one or more of various types of materials that absorb sunlight and generate electrical energy can be selected and applied, such as various organic or inorganic materials.

[0065] As an example, the base plate (20) may be formed of a material having high heat resistance and durability to withstand external factors such as heat supplied from a temperature control unit (30) and light and bias applied from an energy application control unit (40).

[0066] The temperature control unit (30) can be formed to control the temperature of the spare solar module (10). As a specific example, the temperature control unit (30) can control the temperature of the spare solar module (10) by supplying heat to the base plate (20) on which the spare solar module (10) is placed.

[0067] As an example, the temperature control unit (30) may be placed under the base plate (20). For example, the base plate (20) may be placed between the spare solar module (10) and the temperature control unit (30).

[0068] As an example, the temperature control unit (30) may include a heat supply unit formed to supply heat to the base plate (20). The heat supply unit may be formed on one side of the temperature control unit (30). As a specific example, the temperature control unit (30) may increase the temperature of the spare solar module (10) placed on the base plate (20) by supplying heat to the base plate (20) through the heat supply unit. In addition, the temperature control unit (30) may control the temperature decrease speed of the spare solar module (10) placed on the base plate (20) by adjusting the speed at which heat is supplied to the base plate (20) through the heat supply unit.

[0069] As an example, the temperature control unit (30) may include a temperature measuring unit formed to measure the temperature of the spare solar module (10). The temperature measuring unit may be formed on one side of the temperature control unit (30). As a specific example, the temperature control unit (30) may check the temperature of the spare solar module (10) measured by the temperature measuring unit and control the supply speed of heat supplied to the base plate (20).

[0070] The energy application control unit (40) may be formed to apply at least one type of energy to the spare solar module (10). As a specific example, the energy application control unit (40) may be formed to face the spare solar module (10), and for example, may be formed to face the other side corresponding to one side of the base plate (20) on which the temperature control unit (30) is arranged.

[0071] In other words, with reference to FIG. 1, the spare solar module (10) may be placed on the upper surface of the base plate (20), and the energy application control unit (40) may be placed so as to face the upper surface of the spare solar module (10).

[0072] As an example, the energy application control unit (40) may be configured to apply a bias to the spare solar module (10). As a specific example, the energy application control unit (40) may be configured to apply current and voltage to the spare solar module (10).

[0073] As an example, the energy application control unit (40) may be configured to irradiate light to a spare solar module (10).

[0074] As an example, the energy application control unit (40) may be configured to simultaneously apply bias and light to the standby solar module (10).

[0075] Additionally, as another example, the energy application control unit (40) may include one or more members to apply different energies to the standby solar modules (10).

[0077] For example, by using a spare solar module (10), the deterioration phenomenon occurring during the manufacture of solar modules can be reduced or prevented.

[0078] As a specific example, when a high-temperature (e.g., about 150 degrees or higher) laminating process is performed in manufacturing a solar module, after that, heat is supplied to a spare solar module (10) placed on a base plate (20) through a temperature control unit (30) using the solar module manufacturing device (1) of the present embodiment, and one or more types of energy are applied using an energy application control unit (40), so that a solar module with improved heat resistance and stability can be easily manufactured.

[0079] FIG. 2 is a drawing for explaining a solar module manufacturing device according to another embodiment of the present invention.

[0080] Referring to FIG. 2, the solar module manufacturing device (100) may include a spare solar module (110), a base plate (120), a temperature control unit (130), and a bias application unit (140). For convenience of explanation, the differences from the aforementioned embodiment will be described below.

[0081] As an example, a solar module manufacturing device (100) may include a closed chamber that may not be affected by external environmental factors in controlling temperature, pressure, etc., and the contents related to the chamber may be appropriately modified and applied within a range substantially the same as or similar to that described in the above-described embodiment, so a detailed description thereof will be omitted.

[0082] The spare solar module (110) that can be placed on the base plate (120) of the present embodiment can include at least one member that implements a solar cell function, and the type or shape thereof can be varied, and the specific details can be appropriately modified and applied within a range substantially the same as or similar to that described in the above-described embodiment, so a specific description thereof is omitted. The base plate (120) can be formed so that the spare solar module (110) can be placed on it, and the specific details can be appropriately modified and applied within a range substantially the same as or similar to that described in the above-described embodiment, so a specific description thereof is omitted.

[0083] The temperature control unit (130) can be formed to control the temperature of the spare solar module (110), and the specific details can be appropriately modified and applied within a range substantially the same as or similar to that described in the above-described embodiment, so a specific description is omitted.

[0084] The bias application unit (140) may be formed to apply a bias to the spare solar module (110). As a specific example, the bias application unit (140) may be formed to face the spare solar module (110), and for example, may be formed to face the other side corresponding to one side of the base plate (120) on which the temperature control unit (130) is arranged.

[0085] In other words, with reference to FIG. 2, the spare solar module (110) may be placed on the upper surface of the base plate (120), and the bias application unit (140) may be placed so as to face the upper surface of the spare solar module (110).

[0086] As an example, the bias application unit (140) can apply voltage to the standby solar module (110).

[0087] As a specific example, the bias application unit (140) can perform a variable voltage (IV sweep) application to the spare solar module (110). The bias application unit (140) can apply a voltage in the range of 0.1 V to (open circuit voltage value (VOC) + 10.0) V, preferably 0.1 V to (VOC + 5.0) V, and more preferably 0.1 V to (VOC + 1.0) V to the spare solar module (110). For example, the bias application unit (140) can repeatedly apply a variable voltage from the start voltage to the end voltage to the spare solar module (110) by setting a start voltage and an end voltage.

[0088] As a specific example, the bias application unit (140) applies the maximum power conversion voltage (V) to the spare solar module (110). MPP ) can be applied. The maximum power conversion voltage refers to the voltage at which the solar module provides maximum output.

[0089] As a specific example, the bias application unit (140) can apply a constant voltage to the spare solar module (110). The bias application unit (140) can apply a fixed voltage between 0.1 V and (open circuit voltage value (VOC) + 10.0) V to the spare solar module (110).

[0090] As an example, the bias application unit (140) can apply current to the standby solar module (110). As a specific example, the bias application unit (140) can apply a constant current to the standby solar module (110). The bias application unit (140) can apply a current in the range of -50% to +50% of the short-circuit current value (Isc, A), preferably -30% to +30% of the short-circuit current value (Isc, A), and more preferably -10% to +10% of the short-circuit current value (Isc, A) to the standby solar module (110).

[0091] As an example, the bias application unit (140) may apply a bias to the spare solar module (110) until the temperature of the spare solar module (110) is lowered to a set temperature. As a specific example, the bias application unit (140) may apply a bias from the point at which the temperature of the spare solar module (110) is 100°C until the temperature is lowered to 60°C.

[0092] The solar module manufacturing device (100) of the present embodiment can apply at least one of current and voltage to the spare solar module (110) using a bias application unit (140) while the spare solar module (110) is placed on the base plate (120), thereby improving the heat resistance and stability of the spare solar module (110).

[0093] For example, by using a spare solar module (110), the deterioration phenomenon occurring during the manufacture of a solar module can be reduced or prevented.

[0094] As a specific example, when a high-temperature (e.g., about 150 degrees or higher) laminating process is performed in manufacturing a solar module, then, by using the solar module manufacturing device (100) of the present embodiment, heat is supplied to a spare solar module (110) placed on a base plate (120) through a temperature control unit (130), and at least one of a current and a voltage is applied using a bias application unit (140), so that a solar module having improved photovoltaic conversion efficiency (PCE, %), open circuit voltage (Voc, V), and fill factor (FF, %) can be easily manufactured. A solar module having an improvement of 0.1% to 30%, respectively, can be easily manufactured.

[0095] Fig. 3 is a perspective view schematically illustrating an optional embodiment of the solar module manufacturing apparatus of Fig. 2. Fig. 4 is a plan view of the solar module manufacturing apparatus of Fig. 3 viewed from one direction. Fig. 5 is a side view of the solar module manufacturing apparatus of Fig. 3 viewed from one direction.

[0096] Specifically, FIG. 4 is a drawing viewed from the top of FIG. 3 in the Z-axis direction, and FIG. 5 is a drawing viewed from one side in the X-axis direction of FIG. 3.

[0097] Referring to FIGS. 3 to 5, the solar module manufacturing device (200) may include a base plate (220), a temperature control unit (230), a bias application unit (240), and a fixing unit (250). For convenience of explanation, differences from the aforementioned embodiment will be described.

[0098] As an example, a solar module manufacturing device (100) may include a closed chamber that may not be affected by external environmental factors in controlling temperature, pressure, etc., and the contents related to the chamber may be appropriately modified and applied within a range substantially the same as or similar to that described in the above-described embodiment, so a detailed description thereof will be omitted.

[0099] The spare solar module that can be placed on the base plate (220) of the present embodiment can include at least one member that implements a solar cell function, and its type or shape can be varied, and the specific details can be modified and applied within a range substantially the same as or similar to that described in the above-described embodiment.

[0100] The base plate (220) can be formed so that a spare solar module can be placed, and the specific details can be appropriately modified and applied within a range substantially the same as or similar to that described in the above-described embodiment, so a specific description is omitted.

[0101] As one embodiment, the base plate (220) may be formed on the inside of the solar module manufacturing device (200). Additionally, as another embodiment, the base plate (220) may be formed at a position spaced apart from the periphery of the chamber (201) by a preset distance.

[0102] The temperature control unit (230) can be formed to control the temperature of the spare solar module, and the specific details can be appropriately modified and applied within a range substantially the same as or similar to that described in the above-described embodiment, so a specific description is omitted.

[0103] The bias application unit (240) may be formed to apply a bias to the spare solar module. As a specific example, the bias application unit (240) may be formed to face the spare solar module, for example, may be formed to face the other side corresponding to one side of the base plate (220) on which the temperature control unit (230) is arranged.

[0104] In other words, with reference to FIG. 3, the spare solar module may be placed on the upper surface of the base plate (220), and the bias application unit (240) may be placed so as to face the upper surface of the spare solar module.

[0105] Additionally, as an optional embodiment, the bias application unit (240) may be formed to face one side of the base plate (220) on which the temperature control unit (230) is arranged.

[0106] As an example, a bias applied through a bias application unit (240) may be transmitted to the spare solar module through a conductive region of the spare solar module. As a specific example, the bias application unit (240) may apply a bias to a bus bar (211), which is a conductive region of the spare solar module, thereby applying at least one of a current and a voltage to the cathode and the anode of the spare solar module.

[0107] As an example, the bias applying unit (240) may be formed to include an electrode unit (241) that supplies power to the spare solar modules. For example, the bias applying unit (240) may include a plurality of electrode units (241). For example, the bias applying unit (240) may include a number of electrode units (241) corresponding to the number of spare solar modules arranged on the base plate (220).

[0108] As a specific example, the electrode part (241) may be formed in the shape of a robot arm. The electrode part (241) formed as a robot arm may move to the location where the mother wire of the solar module is located through the movement of the joint.

[0109] As an example, the bias application unit (240) may include a position identification unit configured to recognize the position of the solar module. As a specific example, the position identification unit may be configured in the form of an imaging device such as a camera or an infrared recognition device. The bias application unit (240) may determine, through the position identification unit, whether the spare solar module is positioned at the correct position on the base plate (220). In addition, the bias application unit (240) may determine, through the position identification unit, whether the busbar (211) of the spare solar module is positioned at the correct position on the base plate (220).

[0110] As an example, the bias application unit (240) may include a movement control unit (242) formed to control the movement of the electrode unit (241). As a specific example, the movement control unit (242) may be formed to be connected to one side of the electrode unit (241) to control the movement of the electrode unit (241).

[0111] As an example, the movement control unit (242) may be formed on one side of the chamber (201). As a specific example, the movement control unit (242) may be formed in a form extending in one direction on one side of the chamber (201).

[0112] In other words, with reference to FIG. 3, the movement control unit (242) can be arranged in a form extending in the x-axis direction on the upper part of the chamber (201), and the electrode unit (241) can move in the x-axis direction along the movement control unit (242) and supply power to the mother wire (211).

[0113] Additionally, as an optional embodiment, the movement control unit (242) may be arranged to move along a direction intersecting the x-axis (e.g., an orthogonal y-axis direction), and a driving unit (not shown) for movement of the movement control unit (242) may be arranged.

[0114] The fixed part (250) can be formed to be arranged on one side of the base plate (220) so that the spare solar module arranged on the base plate (220) is fixed on the base plate (220) without moving.

[0115] As an example, a plurality of fixed parts (250) may be formed on one side of the base plate (220) and the other side corresponding to the one side.
