High efficiency solar cells
From Wikipedia, the free encyclopedia
The use of solar cells for the generation of electricity has been mainly limited by their poor efficiency and high exploitation costs. But over the last years, research has been focussed on developing high efficiency solar cells.
In 2002, the highest reported efficiency for solar cells based on thin films of CdTe is 18%, which was achieved by the research group of prof. I.M.Dharmadasa at Sheffield Hallam University in the United Kingdom. The US renewable energy research facility NREL achieved an efficiency of 19.5% for the solar cells based on copper indium gallium selenide thin films, also known as CIGS. In 2006, NREL testing demonstrated an efficiency of 40.7% using triple-junction solar cells developed by Spectrolab, Inc.
