Abstract

High-performance cascaded-junction quantum dot solar cells (CJQDSCs) are fabricated from as-prepared highly monodispersed lead sulfide QDs. The cells have a high power conversion of 9.05% and a short-circuit current density of 32.51 mA cm. A reliable and effective stratagem for fabricating high-quality lead sulfide quantum dots (QD) is explored through a "monomer" concentration-controlled experiment. Robust QDSC performances with different band gaps are demonstrated from the as-proposed synthesis and processing stratagems. Various potential CJQDSCs can be envisioned from the band edge evolution of the QDs as a function of size and ligands reported here.

摘要

高性能级联结量子点太阳能电池（CJQDSCs）是由制备好的高度单分散硫化铅量子点制成的。这些电池具有9.05%的高功率转换率和32.51 mA cm的短路电流密度。通过“单体”浓度控制实验探索了一种可靠且有效的制备高质量硫化铅量子点（QD）的策略。从所提出的合成和加工策略中展示了具有不同带隙的稳健量子点太阳能电池性能。根据此处报道的量子点带边随尺寸和配体的变化，可以设想出各种潜在的级联结量子点太阳能电池。
