Mitsubishi Attains 18% Efficiency With Poly Si Solar Cells

Mitsubishi Electric has announced that they are achieving 18% conversion efficiency with polycrystalline Si solar cells. These cells are 100μm thick. Apparently the cells are organized in a honeycomb texture that reduces the reflectance. It has been nearly a year since Mitsubishi announced a 17.4% efficiency, the solar moles have been busy.
