Abstract

Abstract : A UV‐sensitive azopolymer and a visible‐light‐sensitive azopolymer are combined with a fluorescent dye and a filter to create a four‐layer solar thermal cell with record efficiency gravimetric energy density. While most azopolymers discharge under visible irradiation, this device can use a true solar spectrum because fluorescent down‐conversion enables storage of light that would otherwise cause discharging.
