1A highly-efficient concentrated perovskite solar cell-thermoelectric generator tandem system显示文摘Concentrated photovoltaic(CPV)has been identified as an effective method to further enhance the efficiency of photovoltaic cells.Previous studies on CPV mainly focused on III-V multi-junction cells.Nevertheless,Ⅲ-ⅤCPV technology is mainly used in niche applications due to its high cost.Here,we use metal-halide perovskite solar cell(PSC)to demonstrate a concentrated photovoltaic-thermoelectric tandem device.The thermoelectric generator(TEG)is utilized to reduce the effect of heat generation under concentrated solar irradiance.Our tandem system achieved a peak power conversion efficiency(PCE)of 25.0%at a solar concentration of 3 suns.This efficiency exceeded that of the single PSC by~4.7%.Our work proves that by controlling the heat flow in concentrated PSC-TEG tandem system,the redundant heat produced by upper PSC can be effectively reused.This tandem structure provides a promising approach to improve the efficiency and stability of PSC under low-concentrated solar irradiation.Yangying Zhou Yanan Chen Qi Zhang Yu Zhou Meiqian Tai Kunihito Koumoto Hong Lin 2021Journal of Energy Chemistry2021,30,8:0
