On Realizing Higher Efficiency Polymer Solar Cells Using a Textured Substrate Platform

Polythiophene:fullerene bulk‐heterojunction solar cells are fabricated on a one‐dimensional photoresist grating of 2 μm pitch and 300 nm height. These dimensions ensure conformal coating of the photovoltaic active‐layer and lead to higher power conversion efficiency due to light‐trapping, especially...

Summary:Polythiophene:fullerene bulk‐heterojunction solar cells are fabricated on a one‐dimensional photoresist grating of 2 μm pitch and 300 nm height. These dimensions ensure conformal coating of the photovoltaic active‐layer and lead to higher power conversion efficiency due to light‐trapping, especially for higher wavelength photons.
