将UV敏感的偶氮聚合物和UV光敏感的偶氮聚合物与荧光染料和滤光片组合以产生具有创纪录效率重量能量密度的四层太阳能热电池。虽然大多数偶氮聚合物在可见光照射下放电,但该设备可以使用真正的太阳光谱,因为荧光下转换能够存储否则会导致放电的光。
A UV-sensitive azopolymer and a visiblelight-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.
