A double-sided solar cell provided with an ion conductive film layer on a surface of a silicon nitride film layer facing away from a substrate of the solar cell, wherein the resistance of the ion conductive film layer is required to be less than the resistance of the silicon nitride film layer, and a rear glass member is specifically attached to a surface of the ion conductive film layer. Since the resistance of the ion conductive film layer is less than the resistance of the silicon nitride film layer, and the ion conductive film layer is in contact with a rear electrode, when positive ions in the rear glass member are being transferred to the ion conductive film layer, the positive ions are transported out of the double-sided solar cell via the rear electrode instead of being gradually transferred to an aluminum oxide film layer to become neutralized with negative charges fixed in the aluminum oxide film layer, and in turn influencing a passivation effect of the aluminum oxide film layer.

Abrégé

A frameless crystalline silicon battery completely anti-PID lightweight assembly (100) and battery plate, the assembly comprising: a front board glass (10), a battery plate (20), a back board (30) and a junction box (40); the battery plate (20) is located between the front board glass (10) and the back board (30); the front board glass (10) is a photovoltaic ultra-white embossed glass of 4.0-5.0 mm thickness; an encapsulation material layer (50) is provided between the battery plate (20)and the front board glass (10), and another encapsulation material layer (50) is provided between the battery plate (20) and the back board (30); the encapsulation material layer (50) is polyolefin; and the junction box (40) is electrically connected to the battery plate (20). The frameless crystalline silicon battery completely anti-PID lightweight assembly (100) ditches an aluminum frame, and meets the load requirement of 5400 pa without the frame; and the assembly completely resists PID, reduces weight and thickness, and has a reduced manufacturing cost, thus greatly extending the service life of the assembly, reducing power degradation when using the assembly, extending the application range of the crystalline silicon assembly, and improving convenience and transportability of the crystalline silicon assembly.
