Qiaoqiang Gan, University at Buffalo assistant professor of electrical engineering, is developing a new generation of photovoltaic cells that produce more power and cost less to manufacture than what’s available today. One of his more promising efforts involves the use of plasmonic-enhanced organic photovoltaic materials. These devices

Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells using natural substrates derived from plants such as trees. By fabricating them on cellulose nanocrystal (CNC) substrates, the solar cells can be quickly recycled in water at the end of their lifecycle. The technology

A new technique developed by University of Toronto Engineering Professor Ted Sargent and his research group could lead to significantly more efficient solar cells by improving efficiency in colloidal quantum dot photovoltaics, a technology which already promises inexpensive, more efficient solar cell technology. Quantum-dot photovoltaics offers the

New research by Yale University scientists helps pave the way for the next generation of solar cells, a renewable energy technology that directly converts solar energy into electricity. Yale engineers have developed a cost-effective new way to improve the efficiency of crystalline silicon solar cells: using thin,

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%. The cells are based on CIGS (copper indium gallium (di)selenide) semiconducting material. Thin-film, lightweight, flexible high-performance solar modules are

Decal-like application process lets you stick thin, flexible solar panels onto virtually any surface, from roofs to window panes and paper Stanford University researchers have developed the world’s first peel-and-stick thin-film solar cells. The thin-film solar cells can be applied to “paper, plastic, and window glass, helmets,
