Reducing Inter-grain Gaps to Stabilize the Outdoor Operation of Perovskite Solar Modules
The grain boundary voids and interfacial delamination driven by environmental stress constitute a critical issue that affects the long-term outdoor operational stability of perovskite solar cells. Here, we developed a grain boundary polymerization strategy using dimethyl itaconate (DMI) monomers to reduce the inter-grain gaps of perovskite film. The reduced inter-grain gaps effectively alleviate the bulk voids and interfacial delamination in the devices and inhibit mobile ion migration out of the perovskite layer. Consequently, we achieved power conversion efficiencies of 25.9% (25.24% certified) in 0.09 cm2 lab-scale cells and 19.2% in 30 cm × 30 cm industrial-scale solar modules. The encapsulated modules retained 93% and 94% of their initial efficiencies for 2000 and 3000 h in damp-heat conditions and at maximum power point tracking, respectively, representing one of the most stable industrial-scale solar modules reported to date. Importantly, these encapsulated modules exhibited steady power output over 25 days of outdoor operation, demonstrating their viability for practical real-world applications.

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.
