New World Record For Efficiency For Solar Cells; Inexpensive To Manufacture

Friday, May 16, 2008 - 15:35 in Physics & Chemistry

Scientists have improved the efficiency of an important type of solar cell from 21.9 to 23.2 percent (a relative improvement of 6 per cent). The efficiency improvement is achieved by the use of an ultra-thin aluminum oxide layer at the front of the cell, and it brings a breakthrough in the use of solar energy a step closer. The costs of applying the thin layer of aluminum oxide are expected to be relatively low.
