ABSTRACT
This work presents laboratory measurements to test the new concept that elastic scattering from micrometer and larger particles can be used to collect sunlight for use in photovoltaic power production. The collector design consists of a layer of particles dispersed across a mirrored glass plate. Photovoltaic cells line the edges of the plate, which receive light that is coupled into the plate via scattering from the particles and partially confined thereafter by total internal reflection. All materials used to construct the collector are low-cost and typically available off the- shelf. The net electrical power produced is compared to a single, bare cell that is directly illuminated by the same light source. This comparison shows a promising trend in terms of the overall collector size that may eventually yield a solar collector producing more power than that produced by the same amount of cell material under direct illumination.
