High efficiency solar cells

From Wikipedia, the free encyclopedia

High efficiency solar cells are solar cells specifically designed to generate electricity in a cost effective and efficient manner.

In 1994, the University of New South Wales reported the highest silicon solar cell efficiency of 24.7% with their PERL cell technology. 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, a Boeing company.

In July, 2007, a University of Delaware team set a new record of 42.8% efficiency.^[1]
