However, the device power conversion efficiency has remained stagnant for years. Deep-level defects, such as sulfur vacancies (VS), cause serious non-radiative recombination of charge carriers. Here we propose a passivation strategy for VS through the heat treatment of the CdS/CZTS heterojunction in an oxygen-rich environment. In this process, VS are occupied by oxygen atoms, suppressing VS defects. In addition, the diffusion of Cd ions to the CZTS absorber layer, and the formation of positive Na–O and Sn–O complexes can passivate related defects. These effects led to a reduced charge recombination and favourable band alignment. We demonstrate a certified efficiency of 11.51% for air-solution-processed CZTS solar cells (bandgap of 1.5 eV) without any extrinsic cation alloying. The study offers insights into defect passivation and performance improvement mechanism of kesterite solar cells.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"59 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143813847","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}

However, the unstable and expensive semiconductive CQD inks make the scaling up of CQD electronics challenging. Here we develop a strategy for engineering the solution chemistry of lead sulfide (PbS) CQD inks prepared from a low-cost direct synthesis method. By creating an iodine-rich environment in weakly coordinating solvents, we convert the iodoplumbates into functional anions, which condense into a robust surface shell. The fully charged electrostatic surface layer prevents aggregation and epitaxial fusion of CQDs, yielding stable inks. By eliminating the fusion-induced inter-band states, we print a compact CQD film with uniformity in three dimensions, flattened energy landscape and improved carrier transport. We achieved a certified efficiency of 13.40% on 0.04 cm2 cells, with a 300-fold increase in active area, scaling up to a 12.60 cm2 module with a certified efficiency of 10%.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"4 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143789716","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 particular, understanding and controlling thermal runaway, an uncontrollable heat generation from continuous exothermic reactions in batteries, is essential for developing high-safety batteries. However, comprehensive safety evaluations at the full-cell level are limited by size requirements (greater than the ampere-hour scale) for performing accelerating rate calorimetry tests that can provide critical information on heat generation during thermal runaway. Further, efficient safety screening is difficult because of substantial quantities of battery materials and costly manufacturing processes. Here we designed cylindrical pouch-type small batteries (~21 mAh, ~0.1 g of cathode active materials) that are highly susceptible to heat generation, thus allowing us to perform full-cell-level accelerating rate calorimetry tests on a laboratory scale. This enables rapid safety screening and early-stage feedback for battery design, which can help accelerate the development of high-safety batteries.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"20 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758569","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}
