Increasing solar cell efficiency by a coating

Solar panels are seen on the Marina Barrage building, with the Singapore Flyer observation wheel, and office and hotel buildings pictured in the background, in Singapore March 25, 2009. Singapore is trying to become a hub for the clean-tech energy sector, having attracted Norway's Renewable Energy Corp (REC) to build the world's largest solar manufacturing plant of its type making solar wafers, cells and panels that harness the sun's energy.

A self-cleaning coating on the surface of solar cells could increase the efficiency of producing electricity from sunlight and reduce maintenance costs for large-scale solar installations.
