NEGF theory of quantum photovoltaic devices
21 Sep 2011 | | Contributor(s):: Urs Aeberhard
Many high-efficiency photovoltaics concepts require an advanced control and manipulation of the optoelectronic properties of the active device structure, leading to a prominent role of low dimensional absorbers such as quantum wells, wires and dots in the implementation of these concepts....
Economic Factors on the Modern Photovoltaic Market
14 Sep 2011 | | Contributor(s):: Gregory T. Forcherio
Photovoltaic research is heavily driven by market demand and "green-energy" hopes of the future. Commercial and utility level thin film photovoltaic systems have almost reached grid parity worldwide, but the residential market, mainly comprised of crystalline and polycrystalline...
Optimum Morphology and Performance Gains of Organic Solar Cells
