However, optimizing the molecular arrangement of donor and acceptor materials within the active layer remains challenging. Here we control the crystallization kinetics of non-fullerene acceptors with a crystallization-regulating agent, acenaphthene. Acenaphthene changes the self-organization of acceptor molecules by inducing a two-step crystallization: it first fixes the packing motif of the acceptor and then refines the crystallized framework, leading to highly oriented acceptors in the active layer. This forms several charge-transport pathways that improve the charge-transport properties of the device. As a result, efficiencies of 20.9% (20.4% certified) and 21% (20.5% certified) are achieved in D18/L8-BO and PM1/L8-BO-X binary organic solar cells, respectively, with a maximum fill factor of 83.2% (82.2% certified). The result is a step forward in the development of organic solar cells. Optimizing the crystallization of the active materials in organic solar cells is challenging. Fu et al. use an acenaphthene additive to induce a two-step crystallization of the non-fullerene acceptor, achieving a certified 20.5% power conversion efficiency.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 10","pages":"1251-1261"},"PeriodicalIF":60.1,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341992","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 report the fabrication of uniform, large-area Cu2ZnSn(S,Se)4 (CZTSSe) films and solar modules from solution. By tuning the thiourea/metal ratio to increase film porosity—thereby promoting more uniform vertical reaction and lateral grain growth—we improved the uniformity of CZTSSe films and achieved a single-cell efficiency of 13.4% and a solar module efficiency of 8.91%. We further optimized the module structure to reduce non-ideal contact and patterning-induced shunt and resistive losses, resulting in a champion CZTSSe module with a National Renewable Energy Laboratory-certified efficiency of 10.1%. This module also exhibits the lowest cell-to-module loss in open circuit voltage and current density among state-of-the-art emerging thin-film solar modules. Our work demonstrates the viability of solution processing to deposit uniform, large-area CZTSSe film and efficient solar modules, advancing the development of the technology.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"7 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145059595","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, conventional methods, including sequential CO2 electrolysis or reverse water–gas shift reaction, depend on energy-intensive CO2 purification; while emerging reactive CO2 capture strategies still face challenges in designing optimal system components that enable efficient electrochemical regeneration without compromising catalytic performance. Here we systematically screen a broad library of amine-based absorbents to establish a design rationale for tandem amine scrubbing and CO2 electrolysis. We identify piperazine as an optimal capture medium and show that its carbamate form can be directly reduced using a nickel single-atom catalyst. This charge-neutral intermediate facilitates spontaneous adsorption, rapid transport and efficient C–N bond cleavage, enabling stable carbon monoxide production alongside in situ amine regeneration. The process achieves an energy efficiency of ~48.8 GJ per tonne CO, offering a scalable and energy efficient pathway towards carbon-neutral chemical feedstocks. Integrating CO2 capture and electrochemical conversion avoids the thermal release of CO2 and thus could potentially lower the energy needed to make useful products from CO2, but choosing optimal system components is still challenging. Here the authors use piperazine alongside a nickel catalyst for capture and achieve high energy efficiency and stable CO production.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 10","pages":"1262-1273"},"PeriodicalIF":60.1,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032042","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, its high volatility and corrosive nature can degrade the perovskite layer and promote the formation of byproducts and pinholes in the hole transport layer under thermal stress, ultimately compromising device stability. Here we introduce a non-volatile, solid-state alternative—4-(N-carbazolyl)pyridine (4CP)—which stabilizes lithium ions and facilitates the formation of lithium bis(trifluoromethanesulfonyl)imide complexes. Perovskite solar cells incorporating 4CP achieve a power conversion efficiency of 26.2% (25.8% certified) and maintain 80% of their initial performance for over 3,000 h at maximum power point tracking. The unencapsulated devices retain 90% of their initial efficiency after 200 thermal shock cycles between −80 °C and 80 °C, and under continuous exposure to 65 °C and 85 °C. The adoption of 4CP could help improve the stability of n–i–p perovskite solar cells.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"35 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025854","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}
