Photonic assisted light trapping integrated in ultrathin crystalline silicon solar cells by nanoimprint lithography

Christos Trompoukis, Ounsi El Daif, Valérie Depauw +2

We report on the fabrication of two-dimensional periodic photonic nanostructures by nanoimprint lithography and dry etching, and their integration into a 1-μm-thin mono-crystalline…
