Thin film solar cells represent the major option for photovoltaic electricity production at economically acceptable costs. Especially cells and modules based on amorphous silicon can be produced on cheap large area substrates and are presently the choice to enter mass production. The understanding of the physical properties of amorphous silicon and amorphous silicon alloys forms the basis for an optimized cell design and the use of appropriate deposition processes. Stacked cell structures and improved interfaces in each single cell minimize the effect of light induced degradation. Multi junction cells of different band gap absorber materials are being developed and are already used which utilize the solar spectrum even better, and lead to higher stabilized efficiencies.
