The word ''amorphous'' literally means shapeless. The silicon is not structured or crystallised on a molecular level as many other types of silicon-based solar cells are. In the past, amorphous solar cells were used for smaller-scale applications, such as pocket calculators, because their power output was relatively low.

While a-Si suffers from lower electronic performance compared to c-Si, it is much more flexible in its applications. For example, a-Si layers can be made thinner than c-Si, which may produce savings on silicon material cost. One further advantage is that a-Si can be deposited at very low temperatures, e.g., as low as 75 degrees Celsius. This allows deposition on not only glass, b…
