Transmissive spectrum splitting multi-junction solar module for hybrid CPV/CSP system

A new scalable, modular hybrid solar power system is designed to generate electricity through two pathways, CPV and CSP, in order to better meet grid energy demands for reliable renewable energy. The key element, a transmissive, spectrum-splitting multi-junction solar module, is modeled and simulated to analyze its electrical, optical, and thermal properties. Optimized designs are proposed to deliver high efficiency visible light-to-electricity conversion while transmitting infrared light to a thermal receiver. Prospective challenges in the upcoming development and fabrication are discussed.
