However, controlling the energy release remains a challenge. Here, we present an electroswitchable, noble-metal-free hybrid catalyst that enables energy release with high activity and selectivity. The MOST system is <i>p</i>-methoxyphenyl-ethyl ester-norbornadiene (mPENBD), which is photoconverted to its energy-rich quadricyclane isomer (mPEQC). A Co<sup>II</sup> porphyrin derivative, anchored as a self-assembled monolayer (SAM) on an atomically defined Co<sub>3</sub>O<sub>4</sub>(111) electrode, catalyzes the back-conversion of mPEQC to mPENBD with exceptional selectivity. Over 100 cycles, no side products were detected, and only minimal deactivation occurred. Most importantly, catalytic activity can be switched on and off via electrode potential due to the reversible conversion between an active Co<sup>II</sup> porphyrin SAM and an inactive Co<sup>I</sup> porphyrin SAM. This electroswitchable catalyst enables precise control of energy release in MOST-based solar energy storage systems.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"223 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As critical components of PSCs, charge transport layers (CTLs) play pivotal roles in advancing device performance by regulating charge transport dynamics, modulating optical properties, and influencing the quality of overlying perovskite absorbers. In recent years, conformal CTLs, featuring full surface coverage, uniform thickness, and precise replication of the underlying substrate topography, have emerged as an ideal structure, enabling multiple efficiency records in PSCs. This review systematically elucidates the fundamental characteristics of conformal CTLs, critically analyzes advanced deposition technologies, and highlights advances in both single-junction PSCs and perovskite-based tandem solar cells (TSCs), with particular emphasis on technical adaptations to achieve CTLs with enhanced conformality or improved compatibility with textured surfaces and delicate perovskite layers. Finally, the current challenges and future research directions for developing high-performance CTLs in PSCs and TSCs are thoroughly discussed.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"609 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we used twin-screw melt extrusion to fabricate a polymer-based high voltage composite cathode. The melt-processed cathode is dense (near zero porosity) and thick (65 μm) and has high active material loading (80 wt %). The active particles are distributed uniformly throughout the melt-processed cathode, unlike the traditional slurry-cast cathode, which exhibits inhomogeneous particle distribution. In the melt-processed cathode, polymer and carbon form separate phases, whereas in the slurry-cast cathode they blend into a single phase. Due to these structural differences, the melt-processed cathode shows smooth charge–discharge profiles, while the slurry-cast cathode shows noisy charging and soft-shorting behavior. This work highlights that twin-screw extrusion as a scalable, solvent-free manufacturing method is advantageous in producing uniform cathodes, which mitigates anode instability.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"150 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144268957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
