Enhanced cell efficiency holds promise for thin film silicon

Abstract:
The achievement of a stabilized efficiency >10%—confirmed by the National Renewable Energy Laboratory for single-junction amorphous silicon photovoltaic (PV) cells—will be a key factor in driving down costs and assuring the long-term competitiveness of thin film silicon technologies in coming years.

The achievement resulted from an extensive research and development program funded by a leading manufacturing equipment supplier, and demonstrates the potential leverage of equipment suppliers to accelerate technology improvements and scale up. This achievement was a result of two key factors: an optimized amorphous silicon junction, and optimized transparent conducting oxide (TCO) layers (zinc oxide) used for the front and back contacts for the cell.
