The path to ultra-high efficient photovoltaics, proceedings of the 3rd workshop held at JRC Ispra, 2-3 October, 2003

Funded under: FP6-SUSTDEV


The search for a substitute for fossil energy sources, the world wide improving environmental awareness and the needs of the growing population in developing countries have increased the interest in photovoltaics as a long term available, environmentally friendly and reliable energy technology. This leads to the search for nem developments with respect to material use and consumption, device design and production technologies as well as new concepts to increase the overall efficiency.
Since 5 years solar cell manufacturing is growing approx. 35 to 40% per year, still with an increasing tendency. The continuation of this growth will be only possible if a continuous introduction of new technologies takes place, made possible by sound fundamental research. So far the technology is based on single-junction solar cells with an efficiency limit of approx. 31%. However, the fundamental physical limits are well above 80%. Currently new concepts are discussed theoretically how to realise solar cells reaching this limit.
