Increased-transparency Photovoltaic Device

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.

1 Independent Claim

  • 1. A method of making a photovoltaic device comprising forming plural layers including a photoactive layer and conductive layers on opposite sides thereof, separated into plural cells each comprising a region of the photoactive layer and conductive electrodes on opposite sides thereof, the photoactive layer being formed by a process that causes each of the regions of the photoactive layer to comprise a first part that comprises light absorbing 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, which first and second parts are in pre-selected locations, or in a pre-selected distribution of locations, across the region of photoactive layer with one of the first and second parts being located in plural separate areas within the other of the first and second parts.
