Here, we report on tertiary phosphine oxides (R3PO) as materials for defect passivation, where photovoltaic performance was investigated depending on the substituents R. Electron-donating ability of the substituents in R3PO was found to play an important role in passivation. Cyclohexyl substituent was better in achieving photovoltaic performance than linear hexyl substituent. The heterocyclic morpholine substituent bearing oxygen and nitrogen in cyclohexyl form further improved photovoltaic performance due to its enhanced electron-donating ability. Compared with an untreated PSC, the trimorpholinophosphine oxide (TMPPO)-treated PSC improved the power conversion efficiency from 21.95% to 23.72%. Additionally, the dark-storage stability test with an unencapsulated device showed that the TMPPO-treated device maintained 92.7% of its initial PCE after 1250 h, while 86.8% was maintained for the untreated device. Three hundred hour-light-soaking of the encapsulated devices revealed that the operational stability of the TMPPO-treated PSC was superior to the untreated device.\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture>\u0000 </div>\u0000 </figure>","PeriodicalId":93174,"journal":{"name":"EcoMat","volume":"6 7","pages":""},"PeriodicalIF":10.7,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eom2.12470","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141506952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these problems, this work incorporates a porous insulating interlayer (Al2O3) in perovskite devices, which effectively mitigates recombination and parasitic leakage current. A systematic investigation of the relationship between shunt resistance, photocarrier generation, and recombination at different light intensities demonstrates the effectiveness of the alumina interlayer in perovskite solar cells under low-light conditions. Moreover, the practicability of the alumina interlayer was demonstrated through its successful implementation in a large-area perovskite solar module (PSM). With bandgap engineering, the optimized PSM achieves a remarkable power conversion efficiency of 33.5% and a record-breaking power density of 107.3 μW cm−2 under 1000 lux illumination.

This study shows that lignin hybridization effectively improves the sensitivity of a Ti3C2Tx MXene-based chemiresistive sensor; under zero-bias operation, lignin hybridization increases the sensitivity to 15 ppm NO2(g) and CO2(g) by 157.38% and 297.95%, respectively.

Consequently, the MXene/lignin hybrid sensor is attractive for room temperature and zero-bias NO2(g) and CO2(g) detection.

Agricultural industries are calling for game-changer technologies to enable productive and sustainable farming. Carbon dots (C-dots) are carbon-based nanoparticles, smaller than 50 nm, exhibiting unique opto-electro-properties. They have been shown to have positive impact on managing diverse biotic and abiotic stresses faced by the crops. Owing to their versatile carbon chemistry, the surface functionalities of C-dots can be readily tuned to regulate plant physiological processes. This review is focussed on establishing the correlations between the physiochemical properties of C-dots and their impacts on plants growth and health.

Despite their exceptional electromechanical properties, lead-containing materials pose severe environmental risks and foster a new era of lead-free piezoelectric materials after decades of research. However, recent comparative assessments of potassium sodium niobate (KNN) versus lead zirconate titanate (PZT) piezoelectric materials proposed that the environmental damage already presented before use due to raw material extraction and processing, invoking concerns on the true greenness of the lead-free alternatives. Nevertheless, many other factors deserve further consideration, for example, reference geometry and life cycle stage. Herein, the comprehensive life cycle assessment is undertaken on PZT and KNN-based ceramics with a unit volume of 0.001 m3 from cradle to gate. Results show that PZT exhibits higher negative impacts than KNN-based counterparts, attributed to lead extraction, processing, and associated environmental emissions. Across primary quantitative impact indicators from toxicity, environmental, and resource aspects, KNN-based ceramics impose fewer risks on the environment and human health, with the overall impact being only 28% of PZT ceramics. Still, more efficient methods are required for KNN-based ceramics to reduce the high energy consumption and emission during extraction and purification of raw material Nb2O5.
