摘要

在本研究中，我们引入了蒸汽诱导给受体界面（VIDAI）方法，通过在给受体界面直接溶剂蒸汽处理来提高双层有机太阳能电池（OSCs）的性能。采用ITO/ZnO/D18/Y6/MoO3/Ag的倒置器件结构，将1-氯萘（CN）和1,8-二碘辛烷（DIO）蒸气直接注入给体层，处理D18和Y6层之间的界面。与未处理的器件相比，含有VIDAI的器件在1个太阳光照下的功率转换效率（PCE）在CN和DIO分别从15.1%提高到16.8%和17.0%，在CN和DIO的室内光照下分别从13.2%提高到14.9%和15.0%。这归功于优化的表面张力和延长的复合寿命。此外，VIDAI方法增强了器件的稳定性，dio处理的器件表现出最高的最大功率点稳定性。这项工作建立了VIDAI作为一种简单有效的策略来优化双层OSCs的效率和稳定性，为其在室外和室内能量收集中的应用铺平了道路。

Vapor Induced Donor–Acceptor Interface to Enhance The Performance of Bilayer Organic Solar Cells

In this study, we introduce the vapor-induced donor–acceptor interface (VIDAI) method to enhance the performance of bilayer organic solar cells (OSCs) through direct solvent vapor treatment at the donor–acceptor interface. Using the inverted device structure ITO/ZnO/D18/Y6/MoO₃/Ag, we applied 1-chloronaphthalene (CN) and 1,8-diiodooctane (DIO) vapors directly to the donor layer to treat the interface between the D18 and Y6 layers. Compared to the nontreated devices, the devices incorporating VIDAI demonstrated improvements in power conversion efficiency (PCE) under 1 sun illumination from 15.1% to 16.8% and 17.0% for CN and DIO, respectively, and for indoor illumination from 13.2% to 14.9% and 15.0% for CN and DIO, respectively. This is attributed to optimized surface tension and improved recombination lifetime. Additionally, the VIDAI method enhanced device stability, with the DIO-treated device exhibiting the highest maximum power point stability. This work establishes VIDAI as a simple, and effective, strategy for optimizing the efficiency and stability of bilayer OSCs, paving the way for their application in both outdoor and indoor energy harvesting.
