According to MIT, researchers at IBM worked with a thin-film solar company in Japan to attain higher solar efficiencies for solar cells using materials that are more abundant than current thin-film cells.
IBM photovoltaic scientists Teodor Todorov and David Mitzi on Friday detailed the findings of a paper that showed the highest efficiency to date for solar cells made from a combination of copper, zinc, tin, and selenium (CZTS). Published in Advanced Energy Materials, the technical paper described a CZTS solar cell able to convert 11.1 percent of solar energy to electricity.
