Thin film solar cells have shown its dominancy over crystalline silicon solar cells in terms of cost, flexibility and ease of fabrication. As manufacturing processes improve, these solar cells are becoming more cost-effective, appealing to both residential and commercial consumers seeking affordable solar options. The technology enabled the creation of printed ultrathin solar cells on flexible fabric, which can be integrated onto the surface of any shape or structure. The global market for thin film solar cells continues to grow at rate of 10.74% expecting the market to reach US$ 41.0 Billion by 2032. Cu(In,Ga)Se2, CdTe, a-Silicon, and GaAs are the most established and commonly used materials in thin film solar cells, with Cu(In,Ga)Se2 leading the market, achieving a module efficiency of approximately 20%. The book chapter provides an overview of the development and current status of Cu(In,Ga)Se2, CdTe, a-Silicon, and GaAs-based solar cells. It also outlines the typical solar cell structure and the commonly used fabrication methods for each material, offering a comprehensive understanding of the existing technology for each type.

摘要

Thin film solar cells have shown its dominancy over crystalline silicon solar cells in terms of cost, flexibility and ease of fabrication. As manufacturing processes improve, these solar cells are becoming more cost-effective, appealing to both residential and commercial consumers seeking affordable solar options. The technology enabled the creation of printed ultrathin solar cells on flexible fabric, which can be integrated onto the surface of any shape or structure. The global market for thin film solar cells continues to grow at rate of 10.74% expecting the market to reach US$ 41.0 Billion by 2032. Cu(In,Ga)Se2, CdTe, a-Silicon, and GaAs are the most established and commonly used materials in thin film solar cells, with Cu(In,Ga)Se2 leading the market, achieving a module efficiency of approximately 20%. The book chapter provides an overview of the development and current status of Cu(In,Ga)Se2, CdTe, a-Silicon, and GaAs-based solar cells. It also outlines the typical solar cell structure and the commonly used fabrication methods for each material, offering a comprehensive understanding of the existing technology for each type.
