Abstract

The invention discloses a manufacturing method of a flexible solar cell front panel. The method comprises the following steps of: performing multi-layer co-extrusion on a raw material for forming a weather-proof layer and a raw material for forming a base layer through a multi-layer co-extrusion device to obtain a co-extrusion layer of the weather-proof layer and the base layer; and arranging a waterproof layer on the surface of the base layer to obtain the front panel of the flexible solar cell. According to the method provided by the invention, the weather-proof layer and the base layer arecompounded together through adoption of the multi-layer co-extrusion process, and the multi-layer co-extrusion process avoids a bonding process of bonding the weather-proof layer and the base layer together by using a binder, so that the steps of the manufacturing method of the front panel of the flexible solar cell are simplified, and the cost is reduced; the co-extrusion layer of the weather-proof layer and the base layer does not need to be bonded by a bonding agent, so that the bonding layer is not formed between the weather-proof layer and the base layer, and compared with the front panelin which the weather-proof layer and the base layer are bonded by the bonding agent in the prior art, the front panel provided by the invention is better in light transmission and thinner in thickness.

Description

technical field [0001] The invention belongs to the technical field of flexible solar cells, and in particular relates to a flexible solar cell front plate, a manufacturing method thereof, and a flexible solar cell. Background technique [0002] Flexible solar cells are a kind of thin-film flexible solar cells. They are light in weight, can be folded and rolled, and are easy to carry. They can even be pasted on the surface of other objects, such as car glass, clothes, etc., and can also be integrated in windows, roofs, and exterior walls. or interior walls. The flexible solar cell consists of sequentially arranged from top to bottom: the battery front plate, the battery core component, and the battery back plate. In practical applications, flexible solar cells are mostly in relatively harsh environments, such as wind and rain, sunlight, dust, hard objects, etc., and will not be replaced and cleaned frequently. Therefore, the requirements for the front plate of the battery a...
