Solar Cells Lecture 2: Physics of Crystalline Solar Cells
19 Aug 2011 | | Contributor(s):: Mark Lundstrom
Solar cell performance is determined by generation and recombination of electron-hole pairs. This tutorial focussing on recombination losses in crystalline silicon solar cells under short-circuit and open-circuit conditions.
A Physical Model for Non-Ohmic Shunt Conduction and Metastability in Amorphous Silicon Solar Cells
16 Aug 2011 | | Contributor(s):: Sourabh Dongaonkar, Souvik Mahapatra, Karthik Yogendra, Muhammad Alam
In this talk we develop a coherent physics based understanding of the shunt leakage problem in a-Si:H cells, and discuss its implications on cell and module level.Sourabh Dongaonkar is with School of Electrical and Computer Engineering, Purdue University, West Lafayette, INKarthik Y and Souvik...

After a review of the overall renewable energy landscape,including the central role of economics, we present here the case thatPV is on the verge of becoming a major source of electrical powerthrough a principle similar to that which underlies the 50 year progressof IC technology - the reduction...
In Search of the Perfect Semiconductor Photon Detector
out of 5 stars
19 May 2008 | | Contributor(s):: Peter Y. Yu
Photon detectors have many important applications, such as in heat sensing, digital cameras, solar cells and x-ray and gamma-ray detection. So far, the most common detectors are based on elemental semiconductors , such as Si and Ge. However, they are by no means perfect in tackling some of the...
Nano Carbon: From ballistic transistors to atomic drumheads
14 May 2008 | | Contributor(s):: Paul L. McEuen
Carbon takes many forms, from precious diamonds to lowly graphite. Surprisingly, it is the latter that is the most prized by nano physicists. Graphene, a single layer of graphite, can serve as an impenetrable membrane a single atom thick. Rolled up into a nanometer-diameter cylinder--a carbon...
