▎ 摘　　要

NOVELTY - The cell has a top incident type structure comprising a UV distributed Bragg reflector (DBR) reflecting layer (9), a UV light absorbing layer (8), an ultra-thin metal electrode, a positive electrode buffer layer, an active layer doped with nano particles (5), negative electrode buffer layer (4), a thick metal electrode (3), a near infrared DBR reflecting layer (2) and a flexible substrate (1). The top incident type structure and a bottom incident type structure form a metal micro-cavity structure. An upper surface of the ultra-thin metal electrode is provided with a metal nanowire. USE - Long wave near infrared and UV light reflection flexible micro-cavity solar cell. ADVANTAGE - The cell can ensure long wave near infrared and UV light reflection when reflecting long-wave near-infrared light and short-wave UV light, enhance light field local coupling intensity of wave band, effectively broaden a light field of a coupling micro-cavity optical structure, provide new idea for solving balance and constraint problem of photoelectric conversion efficiency and visible light transmittance and improve stability of organic photosensitive material molecular structure aging caused by high energy UV light. The cell can obtain high efficiency and self-cooling semi-transparent solar battery, prolong service life, ensure automatic temperature control function and avoid long-time heating influence. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a long wave near infrared and UV light reflection flexible micro-cavity solar cell preparation method.
