Problems solved by technology

[0006] However, this manufacturing method must use laser scraping machine and mechanical force scraping machine to define the effective area of ​​the battery module because the materials must be mixed and coated, and the substrate needs to be heated at high temperature. Expensive, cumbersome to maintain and take a long time to scrape, which affects its pro

Abstract

The invention relates to a method for manufacturing a solar module. In the manufacturing method, an effective coating area is defined by a mesh cover; by using the mesh cover, each layer of film of the solar module can be directly and continuously formed under a vacuum environment, and the effective area of the solar module is not needed to be defined by a laser scraper, a mechanical scraper and other equipment. Therefore, the equipment cost and scraping process of the laser scraper and the mechanical scraper can be saved. The manufacturing method is particularly applied to a solar cell with a copper indium gallium selenium compound semiconductor film, and procedures in the production process can be reduced; therefore, the capacity efficiency can be improved.

Description

technical field [0001] The present invention relates to a method of manufacturing a thin-film solar cell module by using a metal mesh to define a coating area, in particular, a method for manufacturing a solar cell module of a copper indium gallium selenide (CIGS) semiconductor thin film. Sputtering film formation does not need to go through the process of laser scribing and mechanical scribing, thereby reducing the production process procedures and improving production efficiency. Background technique [0002] In recent years, copper indium gallium diselenide solar cells (Copper Indium Gallium Diselenide Solar Cell, hereinafter referred to as CIGS Solar Cell) have been developed since 1997 when the University of Maine (University of Maine) proposed that the battery efficiency is about 6%. The Energy Research Institute (NREL) published the best battery efficiency of 19.9% ​​in 2008, which has high efficiency and long-term stable performance. Therefore, the application range ...
