6 FAQs about [Amorphous silicon solar cell power generation system]

What are the advantages of amorphous silicon based solar cells?

One of the advantages of amorphous silicon–based solar cells is that they absorb sunlight very efficiently: the total thickness of the absorbing layers in amorphous silicon solar cells is less than 1 μm. Consequently, these layers need to be supported on a much thicker substrate.

Can amorphous silicon solar cells produce low cost electricity?

The efficiency of amorphous silicon solar cells has a theoretical limit of about 15% and realized efficiencies are now up around 6 or 7%. 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.

When did amorphous silicon solar cells come out?

Amorphous silicon solar cells were first introduced commercially by Sanyo in 1980 for use in solar-powered calculators, and shipments increased rapidly to 3.5 MWp by 1985 (representing about 19% of the total PV market that year). Shipments of a-Si PV modules reached ~40 MWp in 2001, but this represented only about 11% of the total PV market.

How are amorphous silicon solar cells made?

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.

How efficient are amorphous solar cells?

The overall efficiency of this new type of solar cell was 7.1–7.9% (under simulated solar light), which is comparable to that of amorphous silicon solar cells .

What are the disadvantages of amorphous silicon solar cells?

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.
