Abstract: A photovoltaic cell comprises first and second electrode layers, an organic photoactive layer between the first and second electrode layers, and a polymeric grating structure in the first electrode layer. The first and second electrode layers are configured to collect electrical charges from the photoactive layer and to allow light to transmit through the first electrode layer to reach the photoactive layer. The grating structure is configured to provide a grating periodicity of about 100 nm to about 500 nm and grating amplitude of about 100 nm to about 500 nm. A device comprising the photovoltaic cell is disclosed. A photovoltaic cell may be formed by printing a polymer on a substrate to form a grating structure, forming a first electrode layer on the polymeric grating structure and the substrate, forming an organic photoactive layer above the first electrode layer, and forming a second electrode layer above the photoactive layer.
