Sanyo Achieves 22.3% Solar Cell Efficiency

Sanyo Electric Co Ltd announced today, that it has achieved a solar cell conversion efficiency of 22.3% with its proprietary technology called "hetero junction with intrinsic thin layer (HIT) solar cell." Although the efficiency was achieved during the research phase, the size of the cell is large enough, 10cm square, to be of a useful size. In June 2007, Sanyo announced that it achieved a cell conversion efficiency of 22.0%. The latest solar cell "broke the barrier of 22-percent conversion efficiency for the first time as a cell with a practical size," the company said. Sanyo aims to enhance the cell conversion efficiency to 23% at the research level, and to 22% or higher at the mass-production level by fiscal 2010.
