Enhanced CO₂ Electrolysis Through Mn Substitution Coupled with Ni Exsolution in Lanthanum Calcium Titanate Electrodes

Abstract In this work, the ligand‐to‐metal charge transition and Förster resonance energy transfer process is exploited to derive lanthanide organic framework (Tb‐cpon) modified perovskite solar cells (PSCs) with enhanced performance under UV irradiation. Tb‐cpon‐modified PSCs exhibit rapid response and reduced degradation due to energy down‐conversion facilitated by effective coupling of UV‐sensitive chromophores to lanthanide luminescent centers, enhancing the spectral response range of the composite films. Furthermore, the characteristic changes of precursor particle sizes suggest formation of Tb‐cpon adducts as intermediate products, leading to enhanced crystallinity and reduced defect concentrations in the Tb‐cpon‐perovskite hybrid film. Accordingly, the Tb‐cpon modified PSC devices obtained a champion efficiency up to 23.72% as well as a sensitive photovoltaic conversion even under pure UV irradiation. Moreover, the unencapsulated devices maintained more than 80% of the initial efficiency after continuous irradiation under a 310 nm UV lamp for 24 h (from the Au electrode side), compared to 21% for the control devices.
