IBPOWER · Intermediate Band Materials and Solar Cells for Photovoltaics with High Efficiency and Reduced Cost

This proposal pursues the manufacturing of intermediate band materials and solar cells according to the following main strategies: a) Insertion of transition elements into III-V semicontuctor matrices; b) use of quantum dot systems to artifficially engineer intermediate band solar cells; c) development of intermediate band materials and solar cells based on InGaN; d) Insertion of transition elements into thin film polycristalline hosts; Approaches “a” to “c” rely on the use of concentrated sunlight to achieve cost competitive goals. Approach “d” relies on low cost materials.
