The elemental ratios affect the amount of Ag to be uniformly incorporated into the chalcopyrite absorber and the open-circuit voltage (<i>V</i>_OC) of the ACIGSe solar cell devices. Ag-containing absorbers deposited at 530 °C achieve a best photoconversion efficiency of 18.2%. Due to an increased <i>V</i>_OC, ACIGSe absorbers perform better than their Ag-free variants at low deposition temperatures. The factors contributing to this increased <i>V</i>_OC of low-temperature devices are: 1) enhanced elemental Ga and In interdiffusion and hence their spatial distribution across the absorber thickness, leading to an increase in the minimum bandgap, 2) an improved absorber crystalline quality with larger grains resulting in high quasi-Fermi-level splitting and lower nonradiative losses. The photoluminescence data obtained on the ACIGSe absorbers reveal the corresponding variations in their bandgap and photoluminescence quantum yield.

However, photothermocatalytic DRM reaction generally needs a high light intensity surpassing 192 kW m⁻² to attain high light-fuel conversion. Also, catalysts applied to photothermocatalytic DRM are liable to inactivation due to carbon deposition. Herein, a nanocomposite of Ni nanoparticles supported on Ni- and Y-doped Al₂O₃ (Ni/Ni-Y₂-Al₂O₃) is prepared. It achieves high H₂ and CO production rates with a light-to-fuel efficiency (29.2%) at a lower intensity (80.1 kW m⁻²). Meanwhile, it sustains excellent photothermocatalytic durability and accomplishes a 37-fold reduction in carbon deposition rate compared to Ni/Al₂O₃. The substantially enhanced catalytic activity and carbon resistance of Ni/Ni-Y₂-Al₂O₃ are correlated with accelerating carbon species (C*) oxidation (the rate-determining steps of DRM). This acceleration derives from the synergetic effect and carbonate species resulting from Y doping, which participate in C* oxidation via two separate reaction pathways. When in light, the synergetic effect further facilitates C* oxidation. Simultaneously, light immensely reduces activation energy, activates the Ni<span></span>O bonds at the interface region, and expedites the reaction between carbonate species and C* in the interface, enhancing catalytic activity and carbon resistance.</p>","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 5","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a two-terminal triple-junction cell, maximizing the open-circuit voltage (<i>V</i>_OC) is not straightforward as it requires understanding and mitigating the dominant losses in such a complex structure.
