Learn MoreUsed as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally feature low efficiency.
I) Lower Efficiency: While efficiency has improved over time, amorphous silicon solar cells generally have lower efficiency compared to some crystalline silicon counterparts. II) Degradation Over Time: These solar cells may experience performance degradation over time, reducing their overall lifespan and efficiency.
Amorphous silicon has more tolerance for defects than crystalline. If a portion of an amorphous silicon thin film solar panel is damaged, it does not have a large effect on the overall power output.
Amorphous and crystalline solar panels differ in their structure and efficiency. Crystalline solar panels are the traditional silicon panels, which are cheaper and can cost half the price or less per watt (compared to amorphous). However, they are not always the best choice due to their lower efficiency and susceptibility to failure in the field.
Hydrogenated amorphous silicon (a-Si:H) has a sufficiently low amount of defects to be used within devices such as solar photovoltaic cells, particularly in the protocrystalline growth regime. However, hydrogenation is associated with light-induced degradation of the material, termed the Staebler–Wronski effect.
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.
