<p>A solid state photovoltaic device is formed on a substrate and includes a photoactive channel layer interposed between a pair of electrodes. The photoactive channel layer includes a first material which absorbs light and operates as a hole carrier. Within the first material are nanoparticles of a second material which operate as electron carriers. The nanoparticles are distributed within the photoactive channel layer such that, predominantly, the charge path between the two electrodes at any given location includes only a single nanocrystal. Because a majority of electrons are channeled to the electrodes via single nanocrystal conductive paths, the resulting architecture is referred to as a channel architecture.</p> |
