progress. Crystalline silicon (c-Si) dominates the wafer-based solar cells. On the other hand, amorphous silicon (a-Si) plays a vital role in thin-film solar cells. Yet, both types of solar cells employ silicon.
The absence of a crystal lattice in amorphous silicon allows for a more straightforward manufacturing process and reduces material waste. The working principle of amorphous silicon solar cells is rooted in the photovoltaic effect. Here is a complete structure of the mechanism of the cells.
At its core, the amorphous silicon solar cell structure comprises of a thin layer of non-crystalline silicon. This thin film is typically deposited onto a substrate, creating a flexible and lightweight structure. The absence of a crystal lattice in amorphous silicon allows for a more straightforward manufacturing process and reduces material waste.
The manufacture of amorphous silicon photovoltaic cells is based on plasma-enhanced chemical vapor deposition (PECVD), which can be used to produce silicon thin film. Substrate can be made of the flexible and inexpensive material in larger sizes, for example stainless steel or plastic materials. The process is the roll-to-roll method.
Most of the important differences in the physics of a-Si based solar cells and crystalline silicon solar cells are a direct result of the most fundamental difference in the materials -the large density of localised gap states in a-Si:H.

Amorphous solar panels operate similarly to their monocrystalline counterparts, by using the photovoltaic effect. However, the key difference between amorphous and monocrystalline solar panels lies in their structure. Amorphous panels function by using thin layers of silicon rather than a single crystal structure.
