Abstract
This Core project developed III-V photovoltaics for terrestrial applications, focusing on high efficiency architectures and on cost-reduction. III-V cells have demonstrated the highest efficiencies of any photovoltaic materials system, reaching over 30% for two- junction tandems and over 47% for more complex concentrator cells. III-Vs have other characteristics that make them attractive to a range of terrestrial and near-terrestrial energy applications, such as being direct absorbers, lightweight and potentially flexible, having good thermal coefficient, good radiation hardness, and being very stable and durable. Cost is a key challenge with III-Vs, however, because of the high cost of epitaxy and processing.
