Design Proposed For A Efficient Thin Film Solar Cell

October 29, 2020 | Leave a Comment

A Penn State research team suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency. Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind the more expensive, crystalline solar cells in efficiency. […]

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 […]
