Solar cell module and manufacturing method thereof

Abstract

The invention discloses a solar cell module and a manufacturing method thereof. The base of the solar cell module is made of mica. The mica has great performances of insulation, heat resistance, acid resistance, alkali resistance and stripping. The mica can be stripped into a base of any thickness and with a smooth surface according to a need. The surface of the stripped mica base is very clean. When the thickness is 30 microns to 100 microns, the mica base has a great bending performance. Using the mica base to manufacture the solar cell module has the advantages that the mica base can be used to manufacture a hard solar cell module and can be used to manufacture a flexible solar cell module; the application field of the solar cell module is greatly expanded; the surface of the stripped mica base is smooth; the stripping process is very simple and easy; cleaning the base is not needed before a solar cell is formed on the mica base; and quick disassembly of the solar cell module can be realized.

Description

technical field [0001] The invention belongs to the field of thin-film solar cells, and in particular relates to a method for making a solar cell module by using a mica substrate. The stripping performance of the mica substrate can make the manufacturing method of the solar cell module more flexible. Background technique [0002] Energy is the driving force for the development of human society and an important material basis for the development of the national economy and the improvement of people's living standards. Conventional energy (mainly fossil energy such as coal, oil, and natural gas) widely used at present is limited, and years of excessive development and utilization have caused serious environmental problems, restricting economic and social development. Therefore, the development of renewable energy is one of the key issues related to the national sustainable development strategy. Among various renewable energy sources, solar photovoltaic power generation techno...

Problems solved by technology

[0009] One of the problems to be solved by the present invention is that the existing solar cell substrate has a single application and cannot be used flexibly; the second problem to be solved by the present invention is that the existing solar cell substrate cannot simultaneously have the advantages of high surface smoothness and low manufacturing cost; The third problem to be solved by the invention is that before forming the solar cell, the substrate needs to be thoroughly cleaned, so that the manufacturing process of the solar cell is complicated and the manufacturing cycle is long; the fourth problem to be solved by the invention is that the formed solar cell is difficult to disassemble and is easy to cause The damage of the solar cell is not convenient for the recycling of the solar cell
