Description

technical field [0001] The invention relates to an amorphous silicon solar cell and a preparation method thereof. Background technique [0002] With the increasingly serious energy crisis and environmental pollution, the development of renewable clean energy has gradually become one of the major international strategic issues. Solar energy is an inexhaustible clean energy source, therefore, the development and utilization of solar energy has become a strategic decision for sustainable development in the energy field of countries all over the world. According to different materials, solar cells are mainly divided into: monocrystalline silicon solar cells, polycrystalline silicon solar cells, amorphous silicon solar cells, II-VI polycrystalline thin-film solar cells and III-V compound solar cells. Among them, traditional crystalline silicon solar cells and semiconductor compound solar cells have always occupied an important position in the market due to their high conversion ...
