Nevertheless, since 2018 the record efficiency of such solar cells has stagnated at 11%, largely due to carriers recombining before they are collected. Here we demonstrate enhanced carrier collection in devices annealed in a hydrogen-containing atmosphere. We find that hydrogen is incorporated mainly in n-type layers and on the absorber surface. Furthermore, we show that the hydrogen treatment triggers the out-diffusion of oxygen and sodium from the absorber bulk to the surface, favourably diminishing the acceptor concentration at the surface and increasing the p-type doping in the bulk. Consequently, Fermi-level pinning is relieved and carrier transport in the absorber is facilitated. We achieve a certified efficiency of 11.4% in Cd-free devices. Although hydrogenation already plays a major role in silicon photovoltaics, our findings can further advance its application in emerging photovoltaic technologies.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"6 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142968163","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}

Here we assess their techno-economic competitiveness against incumbent lithium-ion batteries using a modelling framework incorporating componential learning curves constrained by minerals prices and engineering design floors. We compare projected sodium-ion and lithium-ion price trends across over 6,000 scenarios while varying Na-ion technology development roadmaps, supply chain scenarios, market penetration and learning rates. Assuming that substantial progress can be made along technology roadmaps via targeted research and development, we identify several sodium-ion pathways that might reach cost-competitiveness with low-cost lithium-ion variants in the 2030s. In addition, we show that timelines are highly sensitive to movements in critical minerals supply chains—namely that of lithium, graphite and nickel. Our modelled outcomes suggest that being price advantageous against low-cost lithium-ion variants in the near term is challenging and increasing sodium-ion energy densities to decrease materials intensity is among the most impactful ways to improve competitiveness.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"21 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142968164","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}
