Abstract: 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.

Abstract: A photovoltaic device comprises plural layers separated into plural cells, each comprising a region of a photoactive layer and electrodes on opposite sides thereof. Each of the regions of the photoactive layer are formed comprising a first part that comprises photoactive material and a second part that is not photoactive and that has a greater transmittance of visible light than the light absorbing photoactive material, in pre-selected locations, or in a pre-selected distribution of locations, across the region of the photoactive layer. One of the first and second parts are located in plural separate areas within the other of the first and second parts. The transparency of the photovoltaic device is increased by the transmission of light through the second part that is not photoactive.

Abstract: An optoelectronic device has a layered construction, comprising a base layer, a first conductive layer, a photoactive layer and a second conductive layer. Plural separation channels extending through the photoactive layer and the first conductive layer separate the photoactive layer into photoactive regions, and insulator material extends through the respective separation channels to the base layer. Between adjacent photoactive regions, electrical connectors extend inside the lateral extent of the insulator material between a surface of a second electrode that is in electrical contact with one photoactive region to an opposing surface of a first electrode that is in electrical contact with the other photoactive region. By forming the electrical connectors extend inside the lateral extent of the insulator material, the overall size of the connection is minimised.
