Uncoordinated lead ions can introduce defects during perovskite crystallization, resulting in reduced stability and potential environmental contamination. Here, we synthesized a biomass-derived tetrabutylammonium alginate (TBA-Alg) polymer that forms a connected network at the perovskite surface and grain boundaries to effectively manage lead ions and passivate defects. The alginate groups anchor unbound lead ions, promoting more ordered crystallization, while the hydrophobic tetrabutylammonium chains enhance moisture resistance. The TBA-Alg-modified inverted p-i-n PSCs achieved a PCE of 25.01% and retained 95.5% of their initial performance after 2,000 hours of storage. Under continuous illumination at ~60% relative humidity (RH) for 1050 hours, the devices retained 80% efficiency. Even under water immersion, the TBA-Alg network effectively protected lead ions from water erosion and suppressed 83% of lead leakage. This strategy simultaneously achieves high PCE and stability of lead halide PSCs, and effectively prevents lead contamination; thereby offering the potential to greatly advance the commercialization of lead halide PSCs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"1 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920640","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, a halogen anions pre-homogenizing (Pre-H) strategy was proposed by pre-forming homogeneous inorganic halide precursor to narrow the difference in nucleation rates between the iodide and bromide components, which brings about an improved longitudinal crystallinity, compositional uniformity, and fine contact with the bottom interface. In addition, we found that augmenting proportion of PbBr2 in the precursor template enabled the bandgap of Pre-H perovskite to further expand to 1.78 eV without any phase segregation. Consequently, the single-junction wide bandgap perovskite solar cells (1.68 eV) utilizing the Pre-H strategy achieved an impressive efficiency of 22.12%.

However, there are still fundamental questions that must be addressed.

Strengthened by a statistical analysis of over 5000 publications relating to CO2-electroreduction covering both low- and high-temperature electrolysis for three different product classes (CO, formic acid as well as ethylene/ethanol) conclusions on the most probable employment scenarios for each technology are drawn.
