6 FAQs about [The largest amorphous silicon thin-film solar cell project in China]

What is a thin film solar cell?

Silicon was early used and still as first material for SCs fabrication. Thin film SCs are called as second generation of SC fabrication technology. Amorphous silicon (a-Si) thin film solar cell has gained considerable attention in photovoltaic research because of its ability to produce electricity at low cost.

How efficient are amorphous silicon solar cells?

Because only very thin layers are required, deposited by glow discharge on substrates of glass or stainless steel, only small amounts of material will be required to make these cells. The efficiency of amorphous silicon solar cells has a theoretical limit of about 15% and realized efficiencies are now up around 6 or 7%.

What are the three major thin film solar cell technologies?

The three major thin film solar cell technologies include amorphous silicon (α-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe).
