NEGF theory of quantum photovoltaic devices
22 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
16 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
09 Sep 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...
Solar Cell Fundamentals
19 Aug 2011 | | Contributor(s):: Mark Lundstrom, J. L. Gray, Muhammad A. Alam
The modern solar cell was invented at Bell Labs in 1954 and is currently receiving renewed attention as a potential contribution to addressing the world's energy challenge. This set of five tutorials is an introduction to solar cell technology fundamentals. It begins with a broad overview of...
Solar Cells Lecture 1: Introduction to Photovoltaics
19 Aug 2011 | | Contributor(s):: Mark Lundstrom
An introduction to solar cells covering the basics of PN junctions, optical absorption, and IV characteristics. Key technology options and economic considers are briefly presented.
Solar Cells Lecture 2: Physics of Crystalline Solar Cells
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...
