摘要:

近年来, 有机-无机杂化铅卤化物钙钛矿太阳能电池(PSCs)得到了迅猛发展, 其最高光电转换效率已经达到19.3%. 该类型太阳能电池使用的钙钛矿型吸光材料为含Pb的有机-无机杂化铅卤钙钛矿, 从长远来看,Pb的毒性将制约其大规模应用. 本文从减少吸光材料中Pb的含量出发, 尝试用Sr 部分取代Pb制备一系列少铅钙钛矿CH3NH3SrxPb(1-x)I3, 并将其应用于钙钛矿太阳能电池进行光电性能的研究. 研究结果表明, 相比于全Pb 钙钛矿(CH3NH3PbI3)材料, Sr 取代量为30% (x=0.3)时, 所形成的CH3NH3Sr0.3Pb0.7I3光谱吸收大范围增强,但基于此材料制备的电池器件性能明显下降.

Abstract:

Hybrid organic-inorganic lead halide perovskite solar cells (PSCs) have recently undergone rapid progress and exhibit high photoelectric conversion efficiencies of up to 19.3%. As light-absorber in PSCs, the hybrid organic-inorganic lead halide perovskite cannot be used in large-scale applications because of its high Pb content. In this work, we replaced some Pb with Sr to synthesize a novel perovskite CH3NH3SrxPb(1-x)I3 and used it as a light-absorber in PSCs. Compared with CH3NH3PbI3, CH3NH3Sr0.3Pb0.7I3 is a better light-absorber but the corresponding photovoltaic performance in PSCs decreased obviously.

Key words: Perovskite solar cell, Less Pb, Sr replacing, CH3NH3SrxPb(1-x)I3
