摘要

三碘化甲脒铅(FAPbI3)钙钛矿量子点(PQDs)具有理想的带隙能量、高稳定性和溶液可加工性,在光伏应用中具有很大的优势。FAPbI3 PQD固体膜后处理中使用的抗溶剂会显著影响PQD的表面化学性质,从而导致表面配体去除所产生的空位抑制了PQD的光电性能和稳定性。本文研究了不同极性的抗溶剂对FAPbI3 pqd的影响,并选择了一系列有机分子用于pqd的表面钝化。结果表明,乙酸甲酯能在不破坏PQD晶体结构的前提下,有效去除PQD表面配体。后处理过程中使用盐酸苯并脒(PhFACl)作为PQDs的短配体,可以填补PQDs的a位和x位空缺,从而改善PQDs的电子耦合。最后,基于phfacl的PQD太阳能电池(PQDSC)的功率转换效率为6.4%,而传统的PQDSC的功率转换效率为4.63%。该工作为PQDSCs的表面钝化和器件性能的提高提供了参考。

Ligand exchange engineering of FAPbI3 perovskite quantum dots for solar cells.

Formamidinium lead triiodide (FAPbI3) perovskite quantum dots (PQDs) show great advantages in photovoltaic applications due to their ideal bandgap energy, high stability and solution processability. The anti-solvent used for the post-treatment of FAPbI3 PQD solid films significantly affects the surface chemistry of the PQDs, and thus the vacancies caused by surface ligand removal inhibit the optoelectronic properties and stability of PQDs. Here, we study the effects of different anti-solvents with different polarities on FAPbI3 PQDs and select a series of organic molecules for surface passivation of PQDs. The results show that methyl acetate could effectively remove surface ligands from the PQD surface without destroying its crystal structure during the post-treatment. The benzamidine hydrochloride (PhFACl) applied as short ligands of PQDs during the post-treatment could fill the A-site and X-site vacancies of PQDs and thus improve the electronic coupling of PQDs. Finally, the PhFACl-based PQD solar cell (PQDSC) achieves a power conversion efficiency of 6.4%, compared to that of 4.63% for the conventional PQDSC. This work provides a reference for insights into the surface passivation of PQDs and the improvement in device performance of PQDSCs.
