Abstract
The instability of organic–inorganic halide perovskite (OIHP) absorbers continues to hinder the realization of stable photoelectrochemical water splitting. The bias required for the oxygen evolution reaction triggers the accumulation of dissociated ions from the OIHPs, which induces photocorrosion. To impede this ion migration, we propose a cross-linking strategy that involves using thermal-polymerizated trimethylolpropane triacrylate to reinforce the polymeric network within grain boundaries. Moreover, a photo-cross-linked chiral/achiral mixed 2D perovskite is introduced as a spin polarizer to further enhance the PEC performance. The spin polarizability of the spin polarizer is enhanced by inducing an internal strain. The resulting dual-cross-linked chiral 2D/3D perovskite-based anode exhibited an outstanding stability of 255 h, thereby highlighting the effectiveness of the cross-linking strategy in improving the spin-dependent oxygen production and long-term stability. Furthermore, the perovskite-based cathode and anode, combined as an unassisted coplanar device, exhibit a solar-to-hydrogen efficiency of 11.14% and stable operation for 25 h.

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.
