摘要

本研究介绍了专为倒置同质结单材料有机太阳能电池（HOSC）设计的新型供体-π-受体（D-π-A）分子的合成和表征。该研究探讨了对基于三芳基胺的供体基团和π桥的修饰如何影响这些分子的分子结构、光学、电化学和光伏特性。通过系统地修改π桥长度和供体单元强度等特征，该研究旨在提高功率转换效率（PCE）和整体器件性能。虽然 PCE 值相对较低，但研究结果强调了在简单性、稳健性和成本效益之间取得平衡的设计策略，为在有机光伏应用中推进 HOSC 提供了宝贵的见解。

The impact of structural modifications in donor-acceptor systems on homojunction organic solar cell photovoltaic properties

This study presents the synthesis and characterization of novel donor-π-acceptor (D-π-A) molecules specifically designed for inverted homojunction single-material organic solar cells (HOSCs). It explores how modifications in triarylamine-based donor groups and π-bridges impact the molecular organization, optical, electrochemical, and photovoltaic characteristics of these molecules. By systematically modifying features like π-bridge length and donor unit strength, the research aims to improve power conversion efficiency (PCE) and overall device performance. While the PCE values are relatively modest, the findings highlight design strategies that balance simplicity, robustness, and cost-effectiveness, offering valuable insights for advancing HOSCs in organic photovoltaic applications.
