Description

Technical Field

[0001] The present invention relates to the technical field of solar cells, and specifically to an adaptive polyhedral solar cell structure and a preparation method thereof. Background Art

[0002] A solar cell is a thin photoelectric semiconductor sheet that directly generates electricity using sunlight, also known as a "solar chip" or "photovoltaic cell". As long as it is illuminated by light with a certain illumination intensity, it can instantaneously output voltage and generate current in the case of a circuit, which is called solar photovoltaics in physics, abbreviated as PV. A solar cell is a device that directly converts light energy into electrical energy through the photovoltaic effect or the photochemical effect. Crystalline silicon solar cells that work based on the photovoltaic effect are the mainstream, while thin-film batteries that work based on the photochemical effect are still in their infancy.

[0003] Solar cell power generation is made according to the photoelectric properties of specific materials. A black body (such as the sun) emits electromagnetic waves of different wavelengths (corresponding to different frequencies), such as infrared rays, ultraviolet rays, visible light, etc. When these rays irradiate on different conductors or semiconductors, photons interact with free electrons in the conductor or semiconductor to generate current. The shorter the wavelength of the ray, the higher the frequency, and the higher the energy it has. For example, the energy of ultraviolet rays is much higher than that of infrared rays. However, not all wavelengths of rays can convert their energy into electrical energy. It should be noted that the photovoltaic effect has nothing to do with the intensity of the rays. Only when the frequency reaches or exceeds the threshold at which the photovoltaic effect can be generated can current be generated.

[0004] Currently, when the existing solar cell mechanism is in use, since it is installed in a specified area in a fixed manner and the angle is fixed, it cannot receive sunlight throughout the day.

[0028] A preparation method for an adaptive polyhedral solar cell structure, which includes the following steps: S1.

Grow single-crystalline silicon: Grow a single-crystalline silicon rod by the Czochralski method or the zone melting method; S3.

[0029] The working principle of Embodiment 1 is as follows: When in use, first pass an external bolt through the mounting holes on the connecting chassis 29, and the connecting chassis 29 can be restricted and fixed on the support base on the ground. Subsequently, connect the driving motor 24 to the phased array radar multi-angle beam driving module outside, so that the phased array radar multi-angle beam driving module can control the driving motor 24 to start at sunrise. Then, when the driving motor 24 starts, it can drive the fourth transmission gear 28 to rotate. By meshing the fourth transmission gear 28 with the second gear ring 31, when the fourth transmission gear 28 rotates, it can drive the support square seat 32 to rotate through the second gear ring 31. When the support square seat 32 rotates, it can drive the third transmission gear 22 to rotate along the inner circle of the first gear ring 26, so that the third transmission gear 22 can rotate through the first transmission gear 17. When the first transmission gear 17 rotates, it can drive the second transmission gear 20 and the lead screw 16 to rotate simultaneously. When the lead screw 16 rotates, it can drive the sliding sleeve plate 15 to move downward, so that the sliding sleeve plate 15 can drive the connecting base plate 14 to move downward. When the connecting base plate 14 moves downward, it can drive the battery base frame 4 to move downward through the extension plate 6. By sliding the key at the bottom of the support slider 7 in the card slot inside the top of the support guide rail 30, the bottom end of the battery base frame 4 can be allowed to displace towards the end away from the limiting frame 3, facilitating the downward movement of the battery base frame 4. At the same time, by sliding and sleeving the movable side frame 13 on the outer ring of the limiting frame 3, it can ensure that the sliding sleeve plate 15 moves up and down in a straight line. By controlling the driving motor 24 to start through the phased array radar multi-angle beam driving module, the driving motor 24 can be driven according to time, so that the fourth transmission gear 28 can drive the second gear ring 31 to rotate, enabling the solar cell 8 to always face the sun directly, improving the efficiency of the solar cell 8 receiving sunlight. At the same time, when the support square seat 32 rotates, the sliding sleeve plate 15 can move downward, so that the battery base frame 4 can tilt downward, facilitating the solar cell 8 to face the sun at noon directly, improving the efficiency of the solar cell 8 receiving sunlight. When this device is in use, when the sliding sleeve plate 15 moves downward, it can drive the battery base frame 4 to move downward, so that the battery base frame 4 can be in a horizontal posture and face the sun at noon directly. At the same time, when the solar cell 8 is in an upward-tilting posture, it can face the sunlight in the morning and evening, so that the solar cell 8 can always face the sun throughout the day, facilitating the solar cell 8 to receive sufficient light. By rotating the positioning ring 33 inside the rotating groove 27, the support square seat 32 can be supported to rotate. After sunset, by driving the driving motor 24 to start again through the external phased array radar multi-angle beam driving module, the fourth transmission gear 28 can rotate in the reverse direction, so that the support square seat 32 can rotate and reset synchronously. At this time, when the third transmission gear 22 rotates in the reverse direction along the inner circle of the first gear ring 26, it can drive the lead screw 16 to rotate in the reverse direction synchronously, causing the sliding sleeve plate 15 to move upward, so that the connecting base plate 14 can drive the battery base frame 4 to move upward through the extension plate 6. At this time,By sliding the key on the bottom end of the support slider 7 in the slot on the top end of the support guide rail 30, and rotatably mounting the battery base frame 4 between the two support sliders 7, the bottom displacement of the battery base frame 4 is allowed. When the sliding sleeve plate 15 moves upward to the limit position, it can drive the battery base frame 4 to assume an upward-inclined posture, facilitating the battery base frame 4 to face the sunlight in the next morning. Moreover, by placing the battery base frame 4 in an inclined state, the dew accumulated on the solar cell 8 at night can flow along the surface of the solar cell 8, preventing the dew from accumulating on the surface of the solar cell 8. When this device is in use, the phased array radar multi-angle beam drive module controls the drive motor 24 to start, so that the rotation amount of the fourth transmission gear 28 can be controlled over time. Thus, the support square seat 32 can drive the solar cell 8 to always face the sunlight. At the same time, when the support square seat 32 is rotating, the sliding sleeve plate 15 can move downward, enabling the solar cell 8 to move downward, facilitating the solar cell 8 to be vertically aligned with the sun at noon and improving the light acceptance rate of the solar cell 8 to complete the work. Embodiment

[0030] Based on Embodiment 1, as Figure 8 shown, the battery base frame 4 further includes a connecting arm 35 and a cooling fan 36. The connecting arm 35 is fixedly installed at the inner top end of the battery base frame 4, and the cooling fan 36 is fixedly installed on the top end of the connecting arm 35.

[0031] When implementing this embodiment, when the solar cell 8 is in use, heat will accumulate at the bottom end of the battery base frame 4. At this time, the cooling fan 36 can be turned on. By horizontally aligning the cooling fan 36 with the inner bottom end of the battery base frame 4, when the cooling fan 36 starts, it can blow the outside air through the inner bottom end of the battery base frame 4, so that the heat accumulated at the inner bottom end of the battery base frame 4 can be taken away, preventing the phenomenon of heat overload of the solar cell 8 to complete the work.
