Is hydrogenated amorphous silicon suitable for solar photovoltaic cells?

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.

Are amorphous solar panels better than a-Si solar panels?

In contrast, amorphous solar cells maintain their efficiency even in high-temperature environments. So if you live in a hot region like a desert or a tropical area, an amorphous solar panel may be a good choice. The major disadvantage of a-Si panels is their lower efficiency when compared to other options.
