What are thin-film solar cells? Types and description
Thin-film solar cells are the second generation of solar cells. These cells are built by depositing one or more thin layers or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic, or metal. The thickness of the film varies from a few nanometers (nm) to tens of micrometers (µm).
