The film thickness of a thin-film solar cell differs from a few nanometers (nm) to tens of micrometers (µm), that is much thinner than a commercial silicon wafer (~200 μm), which are the base for fabricating conventional silicon solar cells. Thin-film cells are thus thinner, lighter, and have less drag to counter breakage rates.
