Closer to a True Paint On Solar Panel
May 14, 2013 | Leave a Comment
Qiaoqiang Gan, University at Buffalo assistant professor of electrical engineering and his team are developing a new generation of photovoltaic cells that produce more power and cost less to manufacture than what’s available today. Gan is working on the use of plasmonic-enhanced organic photovoltaic materials. These devices don’t match traditional solar cells in terms of [...]

Solar Electricity by Plant Photosynthesis
May 13, 2013 | Leave a Comment
Ramaraja Ramasamy, assistant professor in the University of Georgia (UGA) College of Engineering said, “We have developed a way to interrupt photosynthesis so that we can capture the electrons before the plant uses them to make sugars.” Ramasamy is also a member of UGA’s Nanoscale Science and Engineering Center. The sun is the largest source [...]

Blowing Beyond the Solar Cell Limit
April 22, 2013 | Leave a Comment
The Shockley-Queisser efficiency limit asserts that the ultimate solar cell conversion efficiency can never exceed 34% for a single optimized semiconductor junction. Researchers at MIT have shown they have a way to blow past that limit. That will raise a cheer to an industry in real need of a major boost. Decades of research on [...]

Quantum Dot Photovoltaic Solar Cell Improvement
March 11, 2013 | Leave a Comment
Quantum dot photovoltaics are not market ready just yet, but efficiency and production costs are quite attractive. A new technique developed by University of Toronto Engineering Professor Ted Sargent and his research group could lead to significantly more efficient solar cells. Sargent’s group has devised a new technique to improve efficiency in colloidal quantum dot [...]

Natural Geometry Makes More Efficient Solar Cells
January 29, 2013 | Leave a Comment
Researchers at Northwestern University’s McCormick Department of Mechanical Engineering have developed a new design for organic solar cells that could lead to more efficient, less expensive solar power. The battle on production expense for silicon cells has an estimated 10 times cost disadvantage to coal, transmission and distribution costs. So it’s a long climb. Organic [...]

New World Record for Thin Film Solar Cell Efficiency
January 21, 2013 | Leave a Comment
Scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have developed thin film solar cells on flexible polymer foils with a new record efficiency of 20.4% for converting sunlight into electricity. The new Swiss cells are based on the semiconducting material copper indium gallium (di)selenide (CIGS) that’s already known for its potential [...]

Discovery of an Efficient Solar Cell
January 11, 2013 | Leave a Comment
An international team of scientists working at Berkeley Lab’s Advanced Light Source (ALS), a premier source of X-ray and ultraviolet light beams for research, found that for highly efficient polymer/organic photovoltaic cells, size matters. Organic polymer-based photovoltaic cells are far less expensive to manufacture than silicon-based solar cells. Scientists have long believed that the key [...]
