Thin film solar cells achieve new record energy conversion efficiency

January 21st, 2013 by Empa

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 cells are based on CIGS semiconducting material (copper indium gallium (di)selenide) known for its potential to provide cost-effective solar electricity. […]

Using inexpensive manufacturing methods to produce efficient solar cells

July 25th, 2011 by Science and Technology Facilities Council

A study, published in the Journal Advanced Energy Materials, paves the way for new solar cell manufacturing techniques and the promise of developments in renewable solar energy.  Efficient solar cell structures can be made using simple and inexpensive manufacturing methods – where flexible layers of material are deposited over large areas like cling-film.
