Because only very thin layers are required, deposited by glow discharge on substrates of glass or stainless steel, only small amounts of material will be required to make these cells. The efficiency of amorphous silicon solar cells has a theoretical limit of about 15% and realized efficiencies are now up around 6 or 7%.
The main disadvantage of amorphous silicon solar cells is the degradation of the output power over a time (15% to 35%) to a minimum level, after that, they become stable with light . Therefore, to reduce light-induced degradation, multijunction a-Si solar cells are developed with improved conversion efficiency.
Amorphous silicon can be likewise utilized as the best material for the execution of efficient multi-junction alongside the single-junction solar cells, where different single junction solar cells are in a series connection with each other to improve the open-circuit voltage of the thin-film solar cell , .
Amorphous silicon solar cells are normally prepared by glow discharge, sputtering or by evaporation, and because of the methods of preparation, this is a particularly promising solar cell for large scale fabrication.
The highest efficiency, so far, detailed for single junction planar thin-film hydrogenated amorphous silicon solar cell is 10.2% , . All through the exploration, the designed amorphous solar cell includes three original parts.
If efficiencies of 10% can be reached on large area thin film amorphous silicon cells on inexpensive substrates, then this would be the best approach to produce low cost electricity. Manish Kumar, Arun Kumar, in Renewable and Sustainable Energy Reviews, 2017
