摘要

In this study, we developed semitransparent perovskite (PVSK) photovoltaic (PV) cells with vivid colors, arising from optical interference in the microcavity systems, dependent on the thickness of their indium tin oxide (ITO) optical spacers. After embedding precisely controllable Ag/ITO/Ag microcavity structures, we obtained PVSK cells exhibiting strong coloration: reddish-orange, orange, yellow, yellow-green, yellowish-green, bluish-green, and blue. We obtained an optimized power conversion efficiency (PCE) of 7.2% for a yellow PVSK device under simulated AM 1.5G irradiation (100 mW cm(-2)). This device also exhibited high stability: After storage in the dark for 70 day in an Ar-filled glovebox, its PCE remained consistently high (up to 7.4%). This approach has potential for use in the preparation of highly efficient, inexpensive, and colorful building-integrated PVs.
