There are many preparation methods for amorphous silicon thin film solar panels. These include reactive sputtering, PECVD, LPCVD, etc. The reactant gas is siH4 diluted with H2. The substrates are mainly glass and stainless steel sheets, and the non-grade silicon films made of them can be used to obtain single junction cells and tandem solar cells respectively through different cell processes.
Amorphous silicon solar cells have great potential due to their high conversion efficiency, low cost, and lightweight. But at the same time, because of its low stability, it directly affects its practical application. If it can further solve the problem of stability and improve the conversion rate. Then, amorphous silicon solar cells are undoubtedly one of the main development products of solar cells.
Multi-compound thin film solar cells In order to find a substitute for monocrystalline silicon cells, people have developed solar cells of other materials in addition to polycrystalline silicon and amorphous silicon thin film solar cells. These mainly include gallium arsenide III-V group compounds, cadmium sulfide, cadmium telluride, and copper indium selenide thin film batteries. Among the above-mentioned batteries, although the efficiency of cadmium telluride and cadmium sulfide polycrystalline thin film batteries is higher than that of amorphous silicon thin film solar cells, the cost is lower than that of single-product silicon batteries, and it is easy to mass-produce, but because cadmium is highly toxic, It will cause serious pollution to the environment, therefore, it is not the most ideal substitute for crystalline silicon solar cells. Gallium arsenide III-V compounds and copper indium selenide thin film batteries have received widespread attention due to their high conversion efficiency.
