Description

Technical Field

[0001] This utility model belongs to the field of solar cell technology, specifically relating to a drawer-type solar cell efficiency enhancement machine. Background Technology

[0002] Against the backdrop of rapid development in photovoltaic technology, crystalline silicon solar cells, as mainstream photovoltaic devices, have seen performance improvements become a research hotspot. Crystalline silicon solar cells include silicon heterojunction (SHJ) solar cells, tunneling oxide passivated contact (TOPCon) solar cells, and passivated emitter and back contact (PERC) solar cells. The surface passivation layer of crystalline silicon solar cells, as one of the key factors in improving cell performance, has a development history closely linked to the development of crystalline silicon solar cells themselves.

[0003] In existing technologies, solar cells are transported to a UV light source device via a conveyor belt and then irradiated with UV light to improve the passivation level of the solar cell interface, thereby increasing the photoelectric conversion efficiency of the solar cells. However, existing solar cells rely on conveyor belts for transport, which limits the irradiation time of the solar cells to the speed and length of the conveyor belt. Consequently, it is difficult to calculate and control the irradiation time of the solar cells in milliseconds. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a drawer-type solar cell efficiency enhancement machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drawer-type solar cell efficiency enhancement machine, comprising a machine body, the interior of which is divided into an efficiency enhancement chamber and a power supply chamber. A UV efficiency enhancement mechanism is installed inside the efficiency enhancement chamber. The UV efficiency enhancement mechanism includes an efficiency enhancement component and a support component, with the support component located below the efficiency enhancement component. The support component includes a drawer-type support platform and guide rails. The drawer-type support platform penetrates the machine body and extends into the efficiency enhancement chamber. The guide rails are symmetrically arranged on both sides of the efficiency enhancement chamber near the drawer-type support platform. The two sides of the drawer-type support platform are slidably connected to the guide rails.

[0006] Preferably, the drawer-type support platform has a T-shaped structure, and the horizontal part of the drawer-type support platform abuts against one side of the machine body, while solar cells are placed on the vertical part of the drawer-type support platform.

[0007] Preferably, the drawer-type support platform is made of black plastic under low-intensity irradiation, and is made of high-strength black metal under medium and high-intensity irradiation.

[0008] Preferably, the efficiency enhancement component includes a mounting plate and UV lamp beads, with the UV lamp beads embedded in the mounting plate and the irradiation direction of the UV lamp beads facing the solar cell.

[0009] Preferably, a heat dissipation component is also provided inside the enhancement chamber near the enhancement component above it. The heat dissipation component includes a cooling fan and a mounting bracket. The mounting bracket covers the top of the UV lamp beads, and the cooling fan is fixed to the inner top wall of the mounting bracket.

[0010] Preferably, the power supply room is equipped with a light source controller and a power supply battery. The power supply battery supplies power to the light source controller, UV lamp beads and cooling fan. The light source controller is connected to a host computer and controls the UV lamp beads' on / off state, irradiation time and intensity in real time.

[0011] Preferably, the top of the machine body is provided with a top cover, and the top cover is provided with heat dissipation holes at the position corresponding to the enhancement chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model uses a drawer-type support platform instead of a traditional conveyor belt to carry and move solar cells into the enhancement equipment for enhancement processing. Since the entry and exit of the drawer-type support platform into the enhancement equipment is controlled manually, while the irradiation time and intensity can be operated through a host computer, the irradiation time and intensity of the solar cells can be controlled at will, so that the irradiation time of the solar cells can be accurately calculated and controlled at the millisecond level. By designing experiments with different UV irradiation amounts and combining accurate irradiation intensity data, it is beneficial to conduct a principle analysis of UV enhancement of solar cells.

[0014] (2) The drawer-type support platform of this utility model is set in black, so that the surface of the drawer-type support platform can absorb ultraviolet rays that are not absorbed by the solar cell, reduce stray ultraviolet rays reflected back into the irradiation space, avoid the influence of diffuse reflection on the experimental results, and at the same time ensure that more effective energy is concentrated on the surface of the solar cell, improving irradiation efficiency and uniformity. This drawer-type support platform adopts a fully enclosed design, which can reduce the interference of external stray light on the experimental results and improve the accuracy and repeatability of the experimental results.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: a drawer-type solar cell efficiency enhancement machine, including a machine body 1. The interior of the machine body 1 is divided into an efficiency enhancement chamber 2 and a power supply chamber 3. A UV efficiency enhancement mechanism is provided inside the efficiency enhancement chamber 2. The UV efficiency enhancement mechanism includes an efficiency enhancement component and a support component. The support component is located below the efficiency enhancement component. The support component includes a drawer-type support platform 4 and a guide rail 5. The drawer-type support platform 4 passes through the machine body 1 and extends into the interior of the efficiency enhancement chamber 2. The guide rail 5 is symmetrically arranged inside the efficiency enhancement chamber 2 near the two sides of the drawer-type support platform 4. The two sides of the drawer-type support platform 4 are slidably connected to the guide rail 5.

[0022] like Figure 4 As shown, the drawer-type support platform 4 has a T-shaped structure, and the horizontal part of the drawer-type support platform 4 abuts against one side of the machine body 1. The solar cell 6 is placed on the vertical part of the drawer-type support platform 4. The solar cell 6 is moved along the guide rail 5 by the vertical part of the drawer-type support platform 4, so as to drive the solar cell 6 to move and enter and exit the enhancement chamber 2. At the same time, the vertical part of the drawer-type support platform 4 is provided with a groove that matches the solar cell 6, which helps to make the solar cell 6 exactly below the UV lamp bead 8.

[0023] The drawer-type support platform 4 is made of black plastic under low-intensity irradiation and high-strength black metal under medium and high-intensity irradiation. The black color allows the surface of the drawer-type support platform 4 to absorb ultraviolet rays that are not absorbed by the solar cell 6, reducing stray ultraviolet rays reflected back into the irradiation space and avoiding the influence of diffuse reflection on the experimental results. At the same time, it can ensure that more effective energy is concentrated on the surface of the solar cell 6, improving irradiation efficiency and uniformity.

[0024] like Figure 3As shown, the efficiency enhancement component includes a mounting plate 7 and UV lamp beads 8. The UV lamp beads 8 are embedded in the mounting plate 7 and the irradiation direction of the UV lamp beads 8 is towards the solar cell 6. The medium-short light emitted by the UV lamp beads 8 when powered on irradiates the solar cell 6. The medium-short light can break the free Si-H and Al-OH in the solar cell 6 and passivate the dangling bonds on the crystalline silicon surface using H, thereby improving the passivation level of the solar cell 6 interface and thus improving the cell efficiency and module power.

[0025] like Figure 2 As shown, a heat dissipation component 9 is also provided inside the enhancement chamber 2 near the top of the enhancement component. The heat dissipation component 9 includes a cooling fan and a mounting bracket. The mounting bracket covers the top of the UV lamp beads 8, and the cooling fan is fixed to the inner top wall of the mounting bracket. The cooling fan dissipates heat from the UV lamp beads 8 to prevent high temperature from affecting the normal operation of the UV lamp beads 8.

[0026] The power supply room 3 is equipped with a light source controller and a power supply battery 10. The power supply battery 10 supplies power to the UV lamp beads 8, the light source controller and the cooling fan. The light source controller is connected to the host computer and controls the opening, closing, irradiation time and intensity of the UV lamp beads 8 in real time.

[0027] like Figure 1 As shown, the top of the machine body 1 is provided with a top cover 11, and a heat dissipation hole is provided on the top cover 11 at the position corresponding to the enhancement chamber 2. The machine body 1 is provided with an air inlet hole, which forms a circulation channel with the heat dissipation hole. At the same time, the heat dissipation hole works with the cooling fan to dissipate heat, which helps to improve the heat dissipation efficiency.

[0028] The working principle and usage process of this utility model are as follows: In use, the drawer-type support platform 4 is pulled out, the solar cell 6 is placed on the drawer-type support platform 4, and then the drawer-type support platform 4 is pushed into the efficiency enhancement chamber 2. The two sides of the drawer-type support platform 4 move along the guide rails 5, thereby moving the solar cell 6 to the bottom of the efficiency enhancement module. Then, the power supply battery 10 supplies power to the UV lamp beads 8. The medium-short light emitted by the powered UV lamp beads 8 irradiates the solar cell 6. The medium-short light can break the free Si-H and Al-OH in the solar cell 6 and passivate the dangling bonds on the crystalline silicon surface with H, thereby improving the passivation level of the solar cell 6 interface, and thus improving the cell efficiency and module power. Since the entry and exit of the drawer-type support platform into the efficiency enhancement equipment is controlled by humans, while the irradiation time and intensity can be operated by the host computer, the irradiation time and intensity of the solar cell can be controlled at will, which is beneficial for the principle analysis of the solar cell 6.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
