Photovoltaics, plasmon energy transfer
Photovoltaic devices integrated into a variety of personal and public electronics
Improve design and fabrication of photovoltaic devices by decoupling the three primary functions of the device
This invention proposes to separate the three functions of photovoltaic devices; the transduction of electromagnetic radiation into excited states, the transport of the excited state to a reaction center to be dissociated into its constituent electron and holes, and the transport of the mobile charges to conductive contacts to be utilized in an external circuit. This is accomplished by employing plasmon energy transfer from an element external into the reaction center stack through a device electrode. It allows the material selection to be independently optimized for the optical and electrical requirements of each function of the photovoltaic device. As a result, a wider class of device components can be explored for optical energy gathering antennas including quantum dots, biologically derived light harvesting antennas and films of organic dyes.
