Abstract: Systems, methods and apparatus are disclosed, including a light collector having a plurality of focusing elements and a plurality of light redirecting features that is optically coupled to one or more photovoltaic (PV) cells. In one aspect, the light collector includes half-cylinder shaped lenses that can focus light incident at various angles onto an elongate v-groove in the light guide such that a first portion of the incident light is diverted to one or more PV cells and a second portion of the incident light is transmitted through the light collector to provide illumination.
