Abstract
A photovoltaic device for converting light into electrical power includes a film () of silicon nanoparticles. The silicon nanoparticle film, which can be a multilayer film, has a photoluminescence response and couples light and or electricity into semiconductor layers. A particular example photovoltaic device of the invention include a solar cell that accepts and converts light of a predetermined wavelength range into electrical power. A film containing luminescent silicon nanoparticles is optically coupled to the solar cell. The film has a predetermined thickness. The film responds to incident radiation and produces light or electron response in the predetermined wavelength range that is optically coupled into the solar cell. In preferred embodiments, the film is additionally or alternatively electrically coupled to the solar cell, which produces charge response that is electrically coupled into the solar cell.
