A two junction, four terminal photovoltaic device for enhanced light to electric power conversion using a low-cost dichroic mirror

A low-cost dichroic mirror can be used successfully for solar spectrum splitting to enhance solar to electrical energy conversion. The mirror is optimized for use with a polycrystalline silicon photovoltaic cell pc-Si. With the dichroic mirror simultaneous excitation of a medium-efficient 11.1% commercial pc-Si and a custommade high band gap GaInP cell 12.3%, yields 16.8% efficiency, with both cells operating at maximum power. Our results clearly show that what is missing for this simple low-cost enhancement of Si solar cell efficiency are low-cost high band gap cells. © 2009 American Institute of Physics.
