Due to the dramatic advances in commercial multi-junction solar cells with 40% conversion efficiency, solar concentrator capable of delivering flux levels of hundreds to thousands of suns at high collective efficiency is the key factor for the success of novel Concentrator Photovoltaic (CPV)...

A novel configuration of solar concentrator, which is the non-imaging planar concentrator, capable of producing much more uniform sunlight and reasonably high concentration ratio, is designed and constructed. This design is envisioned to be incorporated in concentrator photovoltaic (CPV)...
