Description
technical field [0001] The invention relates to the technical field of solar cells, in particular to a preparation system and method for a buffer layer of a copper indium gallium selenium thin film solar cell. Background technique [0002] With global warming, deterioration of the ecological environment and shortage of conventional energy, solar energy has become an important strategic decision for the sustainable development of countries. A solar cell is a device that converts solar energy into electrical energy. It has unique properties that exceed resources such as electrical energy and wind energy, and is expected to become an important pillar of the future power industry. Solar cells are mainly divided into silicon solar cells, compound semiconductor thin film cells, organic polymer cells, nanocrystalline cells, organic thin film cells, etc. Among them, copper indium gallium selenide (CIGS) thin-film solar cells are semiconductor thin-film cells. Since CIGS has a direc...
