Technical Field

[0002] Perovskite solar cells are an emerging photovoltaic technology that uses perovskite-structured compounds as light-absorbing materials. They possess high light absorption efficiency, low-cost materials, and flexibility, making them a valuable research and application technology. With advancements in materials science, further breakthroughs are expected, particularly in improving stability, reducing lead usage, and achieving commercial production. In perovskite solar cell production, encapsulation and performance testing are crucial steps. Current common encapsulation methods involve stacking glass or fiberglass sheets with high-transmittance adhesives to the solar cells, protecting them without hindering light conversion.

Spray nozzles are respectively provided on the upper and lower sides of the coater 33, and the opening and closing are controlled by a solenoid valve.
[0030] Operating principle: The battery cells are positioned and installed on the conveyor belt 2, that is, limited by the positioning frame 4, and the battery cell wires are limited in the groove structure of the limiting seat 5; Fiberglass boards are prepared and stacked inside the preparatory frame 16, and the support plate 18 is supported and pushed by the support cylinder 17; the position of the transfer table 19 is controlled by the control cylinder 10, the adsorber 20 adsorbs the fiberglass board, and then the lead screw 8 is driven by the motor 7 to rotate, and the slide 9 slides to transfer the fiberglass board to the processing table 13. The fiberglass board can be fixed by the fixing cylinder 15.
[0031] Subsequently, the position cylinder 38 controls the movement of the transfer table 39, and the planar adsorption part on the adsorber 41 adsorbs the battery cell. The end face of the clamping plate 42 is aligned with the end face of the limiting seat 5, so that the wire is located between the two clamping plates 42. The electromagnetic sliding rod 43 controls the clamping plate 42 to clamp and fix the wire, so that the wire will not swing uncertainly during the transfer of the battery cell, that is, it will be in a fixed state. The battery cell is transferred to the top of the worktable, and the motor 21 drives the lead screw 22 to rotate, the slide 24 to slide, and the motor 37 drives the lead screw 26 to rotate, the slide 28 to slide. The indexing motor 31 controls the deflection of the coater 33, so that the coater 33 is located below the battery cell. Then the transfer box 29 transfers the epoxy resin adhesive, which is sprayed onto the battery cell through the spray nozzle on the coater 33.
[0032] After the spraying is completed, the battery cell is transferred to the processing table 13 and bonded to the fiberglass board. At this time, the planar adsorption part on the adsorber 41 can compact the battery cell and the fiberglass board. It should be noted that when the battery cell is on the processing table 13, the battery cell wire is located on the limiting groove 14 to limit the wire. The upper surface of the battery cell is sprayed with epoxy resin adhesive through the spraying port on the other side of the coater 33. Subsequently, the fiberglass board is transferred to the processing table 13 through the transfer mechanism 2 and bonded to the battery cell. It is then compacted by the planar adsorption part on the adsorber 41.
[0033] After encapsulation, the transfer mechanism 2 adsorbs and transfers the battery cell to the top of the light receiver 11. The light emitter 1101 emits a light source to the battery cell, and the light receiver 11 receives the light that penetrates the battery cell, thereby detecting the light transmittance of the encapsulated battery cell. The detection principle is existing technology and will not be described in detail here.
