A photovoltaic device (1) comprising a base layer (11); a first conductive layer (12) disposed on the base layer (11); a photoactive section (29) disposed on the first conductive layer (12), the photoactive section (20) comprising one or more layers (13, 14, 15); and a second conductive layer (16) disposed on the photoactive section (20). At least one of the layers of the device is optically modified by having a refractive index modifying material distributed therein that modifies the refractive index of the layer at wavelengths of visible light. The refractive index modifying material 8e. g. 30) may take the form of particles that may be dispersed in a layer that comprises a continuous phase of material or assembled particles, or may take the form of a coating on the surfaces of structured material in the layer. By modifying the refractive index of the optically modified layer to be closer to the refractive index of an adjacent layer, scatter from the interface between the layers is reduced. |
