Nanostructured III-V Photovoltaics

The recent demand for alternative energy production has propelled considerable interest in next-generation photovoltaics. The preliminary 2007 Department of Energy report on U.S. energy consumption states that renewable sources account for only 7% of the energy production, with solar energy representing a minuscule 1%. Solar energy is a particularly attractive renewable source given that the sun radiates more energy onto the earth in one hour than the entire human population uses in one whole year.

The Nanostructured Photovoltaics (Nano-PV) approach presents a highly transformative technology, with an overarching goal of making PV cost competitive. The nanomaterials approach to PV device development centers around the fact that the electrical, optical and even thermal properties of these materials can be controlled by changing the particle size. Our focus in this area is for both space and terrestrial applications.
