摘要

近年来钙钛矿材料因其优异的光电性能而成为光伏领域的研究热点, 但调控钙钛矿太阳电池内界面缺陷仍是亟需解决的关键问题之一。本研究在溶液两步法制备钙钛矿光吸收层的过程中引入有机小分子添加剂(L-3-(4吡啶基)-丙氨酸(L-3-(4-pyridyl)-alanine, (PLA))。测试结果显示引入PLA可提高器件的各光电性能参数, 含PLA器件的最优能量转换效率为21.53%, 而参照器件为20.10%。进一步研究表明引入PLA可延长荧光寿命, 降低器件的陷阱态密度(从5.59×1016cm-3降至3.40×1016cm-3), 促进界面电荷抽取, 抑制载流子复合。器件性能的提升是由于PLA促进PbI2在钙钛矿薄膜晶界处富集及PLA在界面处锚定起到了钝化缺陷的作用。本研究可以为进一步调控钙钛矿太阳电池的缺陷提供借鉴。

Abstract

In recent years, perovskite materials become a research hotspot in the field of solar cells due to their excellent photovoltaic properties, but control of their interface defects still remains one of the key problems to be solved. In this study, an organic small molecule additive (L-3-(4-pyridyl)-alanine (PLA)) was introduced in the preparation of perovskite photoabsorption layer by two-step solution method. The characterizations showed that the introduction of PLA could comprehensively improve photoelectric performance of the device, with optimal energy conversion efficiency of 21.53%, in contrast to that of the reference device (20.10%). Further studies showed that PLA could reduce the trap state density of the device from 5.59×1016cm-3 to 3.40×1016cm-3, promote the interface charge extraction, and decrease the carrier recombination. The above improvements can be attributed to the PLA induced PbI2 enrichment at grain boundaries and PLA anchoring at defects, which play an important roles in passivate defects. This study can provide guideline for further regulating the defects of perovskite solar cells.

Key words： perovskite solar cell; additive with multifunctional groups; trap state density; carrier recombination
