Physicist Bram Hoex (29) and colleagues at Eindhoven University of Technology (TU/e), together with the Fraunhofer Institute in Germany, have improved the efficiency of an important type of solar cell from 21.9 to 23.2 per cent (a relative improvement of 6 per cent). This new world record is being presented on Wednesday 14 May at a major solar energy conference in San Diego, USA. 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.
