Problems solved by technology

Traditionally, solar cells and secondary batteries are configured separately, which leads to a large volume of the entire power supply system
At the same time, the discrete solar cells and secondary batteries need to be connected by external lines, which may lead to problems of increased jumpers and poor contact
[0016] 2. The current secondary batteries, such as lithium batteries or button batteries, are usually packaged in metal or hard plastic. On the one hand, it leads to a larger volume. In addition, it is not conducive to flexibly changing the appearance and shape of the secondary battery

Abstract

The invention discloses a lamination type energy-storable solar battery, which is characterized in that: a secondary battery is laminated on a lamination type solar battery; the secondary battery is a lithium ion battery and is provided with a charge control circuit; and all the components are packaged through flexible plastic. The prepared lamination type energy-storable solar battery integrates the solar battery and the lithium ion battery so as to reduce external circuits, improve the compactness, reduce the volume, reduce wire jumper and also ensure high conductivity; and through application of a gel electrode and a plastic packaging process, the moisture resistance is improved, and foldability is achieved. During preparation, a back electrode layer of the solar battery also bears an anode current collector of the lithium ion battery, so that materials can be saved, and the conductivity can be improved at the same time; and an anode active layer, a diaphragm and a cathode active layer of the lithium ion battery can be prepared into sheets in advance to facilitate compounding during the preparation and realize continuous production.

Description

technical field [0001] The invention relates to a method for preparing a solar cell, in particular to a method for preparing a laminated energy-storage solar cell. Background technique [0002] As a kind of clean energy, solar cells have been widely valued and welcomed by the market in recent years, and have penetrated into all aspects of human life, and their production technology has been continuously improved and improved. [0003] Thin-film solar cells have less power loss under the same shading area, and less power loss than wafer solar cells under the same illuminance. They have better power temperature coefficient, better light transmission, and higher cumulative power generation. A small amount of silicon raw material, no internal circuit short circuit problem, thinner than wafer solar cells, and no worry about material supply have been widely promoted and utilized in recent years. In particular, the foldable thin-film solar cell made of amorphous silicon combined w...
