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
20 Aug 2011 | | Contributor(s):: Biswajit ray, Muhammad Alam
Morphology of light absorbing layer is known to dictate the power conversion efficiency of organic photovoltaic (OPV) cell. The innovation of bulk heterojunction (BHJ) led to significant improvement for exciton harvesting, but carrier recombination at the distributed interfaces and variability...
Solar Cells Lecture 4: What is Different about Thin-Film Solar Cells?
29 Aug 2011 | | Contributor(s):: Muhammad A. Alam
Thin film solar cells promise acceptable efficiency at low cost. This tutorial examines the device physics of thin-film solar cells, which generally require a different type of analysis than crystalline solar cells.
Solar Cells Lecture 5: Organic Photovoltaics
Organic solar cells make use of low-cost organic polymers forphotovoltaics. Although these solar cells may appear to be quitedifferent from solar cells made with conventional, inorganicsemiconductors (e.g. they make use of exciton generation rather than electron-hole generation) this...
