摘要

In this study, perovskite solar antenna (PVKSA) is designed and implemented for multifunctional applications. This PVKSA can translate solar energy into electricity and also transmit high-frequency (2.45 GHz) signals with long photovoltaic lifespans and high antenna gains. A perovskite layer and a bottom transparent conducting oxide were used as the ground of the antenna; poly (methyl methacrylate) (PMMA) was used to encapsulate the perovskite solar cell and also as the dielectric layer of the antenna. Electromagnetic simulation was performed to optimize the structure of the PVKSA. The use of a highly conductive oxide film as the bottom electrode of the perovskite solar cell was necessary to markedly increase the antenna gain. Because of the low thickness of perovskite solar cells, the PVKSA's resonant frequency and gain were not influenced by the solar cell; these properties were noted to be superior to those of silicon-based solar cell antennas. The PMMA layer effectively blocked the release of water vapor and oxygen from the perovskite solar cell, thus reducing the formation of the delta phase and other secondary phases. PMMA-encapsulated solar cells sustained approximately 80% of the original power conversion efficiency after 48 h. Furthermore, the influence of the absorber on the resonant frequency and gain of the resonator was reduced. Thus, the proposed multifunctional PVKSAs with long lifespans is useful in communication and electricity generation.
