在具有反向结构的量子点太阳能电池（QDSC）中，量子点层在电子传输层（ETL）和另一个半导体量子点层之间形成两个不同的结。最近对反转结构QDSC的研究表明，QD层之间的结是主要结，而不是ETL和QD层之间的结，这与传统观点相反。然而，迄今为止，对于量子点异质结结构在太阳能电池性能和器件性能中的作用和重要性，还缺乏系统的研究。在本研究中，我们系统地控制了QD结的结构来平衡电荷输运，这表明结的位置对滞后效应、填充因子和太阳能电池性能有显著影响，并归因于平衡电荷输运。
In a quantum dot solar cell (QDSC) that has an inverted structure, the QD layers form two different junctions between the electron transport layer (ETL) and the other semiconducting QD layer. Recent work on an inverted-structure QDSC has revealed that the junction between the QD layers is the dominant junction, rather than the junction between the ETL and the QD layers, which is in contrast to the conventional wisdom. However, to date, there have been a lack of systematic studies on the role and importance of the QD heterojunction structure on the behavior of the solar cell and the resulting device performance. In this study, we have systematically controlled the structure of the QD junction to balance charge transport, which demonstrates that the position of the junction has a significant effect on the hysteresis effect, fill factor, and solar cell performance and is attributed to balanced charge transport.
