Abstract: A light splitting optical module that converts incident light into electrical energy, the module including a solid optical element comprising an input end for receiving light, a first side, and a second side spaced from the first side, a first solar cell adjacent to the first side of the solid optical element, and a second solar cell adjacent to the second side of the solid optical element. The first solar cell is positioned to absorb a first subset of incident light and reflect a first remainder of the incident light to the second solar cell through the solid optical element, wherein the first solar cell has a lower band gap than the second cell.
