Design and Non‐Lithographic Fabrication of Light Trapping Structures for Thin Film Silicon Solar Cells

A self-assembled light trapping structure is numerically designed on the backside of thin film silicon solar cells and fabricated by using porous alumina as a template. We demonstrate this structure can effectively increase the optical absorption and thus improve the solar cell performances.
