Abstract

A spectrum splitter based on micro-prism arrays is demonstrated for laterally arrayed multi-junction concentrator photovoltaic modules. The conjugate micro-optics design delivers high-transmission, efficient spectrum splitting with minimum aberration, a low profile, and low-cost fabrication, thus allowing large-scale production of micro-concentrator photovoltaic modules. A dispersive optic prototype based on a four-prism design is fabricated and characterized through outdoor measurements showing excellent agreement with our design model.
