Solar Clean Energy Utilization - Thin Film Solar Cells (Flexible solar panel)
The application of silicon solar cells is becoming more and more popular, but the expensive raw material has become a bottleneck for development. Thin-film solar cells use very little material because only a very thin layer of photovoltaic material is required. It can be used with soft substrates, and the application flexibility is large, if the technology development is mature, its market will be quite broad. This paper discusses the development overview, technical difficulties, advantages and disadvantages of thin film solar cells, i.e., amorphous silicon thin film solar cells, micro (polycrystalline) silicon thin film solar cells, copper indium selenium thin film solar cells, cadmium telluride thin film solar cells, dye sensitized thin film solar cells and organic thin film solar cells, which have received much attention so far.
