Solar Energy Conversion Efficiency of 47% Demonstrated

• arclein

Solar concentration could reduce the amount of photosensitive material needed by as much as a factor of a hundred or even a thousand. It is well known that efficiency increases when light is concentrated. Prior to this, four-junction solar cells have demonstrated the highest solar conversion efficiency levels, but now, with the adoption of six junctions, the results have greatly improved. A further reduction in series resistance within this structure could realistically allow efficiency levels in excess of 50%.
