摘要

我们通过在锡铅钙钛矿太阳能电池的电子选择触点中引入Cr/Cu双层电极，将热击穿电压从−7.6 V提高到−14.5 V，解决了锡铅钙钛矿太阳能电池的反向偏置不稳定性问题。铬通过减轻热点分流来防止灾难性的设备故障，在反向偏置应力期间形成的I2具有化学稳定性。

Tin–Lead Perovskite Solar Cells with Enhanced Reverse Bias Stability

We address reverse bias instability in tin–lead perovskite solar cells by introducing Cr/Cu bilayer electrodes in their electron-selective contacts, which raise thermal breakdown voltage from −7.6 V to −14.5 V. Chromium prevents catastrophic device failure by mitigating hotspot shunting, being chemically stable against I₂ formed during reverse bias stress.

期刊介绍： ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format. ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology. The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
