All amorphous silicon-based solar cells exhibit such degradation with light, which is called the Staebler–Wronski effect (Staebler and Wronski 1977a, 1977b).The effect anneals out nearly completely within a few minutes at temperatures of about 160 ∘ C, and anneals substantially in outdoor deployment at summer operating temperatures of 60 ∘ C.

In 1978, Wilson [6] used the MIS or Schottky diode structure (Fig. 3) instead of the p-i-n, which led to 4.8% efficiency.The Schottky barrier α-Si solar cell is constructed with a metal-to-N junction rather than a p-n semiconductor junction [6].Schottky barrier α-Si solar cells incorporate a thin, yet highly doped, p-type α-Si, between a Schottky barrier …
Hydrogenated amorphous silicon solar cells were fabricated using solution-based processes.
