Here we reveal a chain-length-dependent and halide-related phase separation problem of 2D perovskite growing on top of three-dimensional perovskites. We demonstrate that a homogeneous 2D perovskite passivation layer can be formed upon treatment of the perovskite layer with formamidinium bromide in long-chain ( >10) alkylamine ligand salts. We achieve champion active-area efficiencies of 25.61%, 24.62% and 23.60% for antisolvent-free processed small- (0.14 cm2) and large-size (1.04 cm2) devices and mini-modules (13.44 cm2), respectively. This passivation strategy is compatible with printing technology, enabling champion aperture-area efficiencies of 18.90% and 17.59% for fully slot-die printed large solar modules with areas of 310 cm2 and 802 cm2, respectively, demonstrating the feasibility of the upscaling manufacturing. Achieving uniform coverage of interfacial layers in perovskite solar cells is challenging, especially over large areas. Li et al. present design guidelines to fabricate these layers with uniform morphology, suppressed defects and improved charge transport.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 12","pages":"1540-1550"},"PeriodicalIF":49.7,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599772","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 develop deployment pathways for four SMR designs displacing natural gas in industrial heat processes at 925 facilities across the United States under diverse policy and factory or onsite learning conditions. We find that widespread SMR deployment in industry requires gas prices above US$6 per metric million British thermal unit, low capital cost over-runs and/or aggressive carbon taxes. At gas prices of US$6–10 per metric million British thermal unit, 7–55 gigawatt-thermal (GWt) of SMRs could be economically deployed by 2050, reducing annual emissions by up to 59 Mt of CO2-equivalent. Of this deployment, 2–24 GWt rely on module manufacturing learning within a factory. Widespread deployment potential hinges on avoiding substantial cost escalation for early investments. Policy levers such as direct subsidies are not effective at incentivizing sustainable deployment, but aggressive carbon taxes and investment tax credits provide effective support for SMR success. Nuclear small modular reactors could help decarbonize industrial heat processes in the United States, but widespread deployment (of up to a thousand reactors) hinges on factory learning, extended tax credits and avoiding cost escalations.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 1","pages":"77-89"},"PeriodicalIF":49.7,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142574597","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 demonstrate a multimodal operando microscopy toolkit to measure and spatially correlate nanoscale charge transport losses, recombination losses and chemical composition. By applying this toolkit to the same scan areas of state-of-the-art, alloyed perovskite cells before and after extended operation, we show that devices with the highest macroscopic performance have the lowest initial performance spatial heterogeneity—a crucial link that is missed in conventional microscopy. We show that engineering stable interfaces is critical to achieving robust devices. Once the interfaces are stabilized, we show that compositional engineering to homogenize charge extraction and to minimize variations in local power conversion efficiency is critical to improve performance and stability. We find that in our device space, perovskites can tolerate spatial disorder in chemistry, but not charge extraction. Conventional microscopy is unable to correlate nanoscale properties of metal halide perovskites with the performance of solar cells. Frohna et al. present a multimodal operando microscopy toolkit as a diagnostic tool to address the issue.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 1","pages":"66-76"},"PeriodicalIF":49.7,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41560-024-01660-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142536881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
