Flexible bendable crystalline silicon solar cell panel

Abstract

The invention discloses a flexible bendable crystalline silicon solar cell panel. The flexible bendable crystalline silicon solar cell panel comprises a plurality of cell panel units which are mutually independent, and are communicated with one another through flexible conductors. Each cell panel unit comprises a tempered glass layer and a crystalline silicon cell piece in sequence from top to bottom, wherein the tempered glass layer and the crystalline silicon cell piece are fixed through adhesive film. The cell panel units are connected through flexible materials. According to the flexible bendable crystalline silicon solar cell panel, a piece of integrated photovoltaic glass used by the flexible bendable crystalline silicon solar cell panel is divided into parts, each part of the photovoltaic glass is combined with each crystalline silicon cell piece of the solar cell panel in a laminated mode to form each cell panel unit, the peripheries of the cell panel units are connected through flexible adhesives or flexible boards, the cell panel units are electrically connected through the flexible conductors, the flexible bendable crystalline silicon solar cell panel which is formed in a splicing mode can be repeatedly bent, and due to the fact that the tempered glass covers the upper layer of the flexible bendable crystalline silicon solar cell panel body, the flexible bendable crystalline silicon solar cell panel has good capacity of resisting external force impact, has solidity as an ordinary cell panel and has a certain flexibility, and the application field of the flexible bendable crystalline silicon solar cell panel is expanded.

Description

Technical field [0001] The invention relates to the field of solar power generation, in particular to a flexible and bendable crystalline silicon solar panel. Background technique [0002] The crystalline silicon solar cell panels in the prior art are basically laminated with a piece of toughened glass on the outer layer to protect the cells. This also makes the cell panels inflexible and limits their application fields. In order to make the crystalline silicon solar panel bendable, the common practice is to remove the outer glass of the solar panel and replace the existing 3.2mm special photovoltaic glass with a hard organic polymer sheet. This has certain disadvantages: on the one hand, the number of bending Too much, it will damage the brittle crystalline silicon cell and affect power generation. On the other hand, it loses the protection of the glass layer, so that when the surface of the solar cell panel is impacted by an external force, the cells in the inner layer will als...

In order to make crystalline silicon panels bendable, the common practice is to remove the glass on the outer layer of the panel and replace the existing 3.2mm dedicated photovoltaic glass with a hard organic polymer sheet. This has certain disadvantages: on the one hand, the number of bending times Too much will damage the brittle crystalline silicon cells and affect power generation. On the other hand, the protection of the glass layer will be lost, so that when the surface of the solar panel is impacted by external forces, the inner cells will also be damaged.
