A new approach in which stability is enhanced is via interface engineering to block moisture access to the hygroscopic photo-absorbers used in perovskite solar cells. In this work, we explored the use of polymer interface layers between the 3D perovskite absorber and the conventional hole transport layer, Spiro-OMeTAD. Specifically, poly-[bis-(4-phenyl)-(2,4,6-trimethylphenyl)-amin] (PTAA) and Poly({4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl}{3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) (PTB7) were examined in the regular structure, but these are mostly utilized as hole transporting layers in an inverted structure. Specifically, the effect of inserting PTAA and PTB7 layers, as buffer layers at the interface between the absorber layer and hole transporting layer in perovskite solar cells is investigated. The power conversion efficiency of perovskite solar cells decreased from 16.49% when using PTAA to 12.73% using PTB7.","PeriodicalId":19015,"journal":{"name":"MRS Advances","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135342367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers at Pacific Northwest National Laboratory constructed a chamber that complies with the requirements needed for an atmospheric reaction platform and the safety principles of interacting with hazardous dispersible sources to enable the environmental testing of these gases. Initial dynamic testing showed inter-chamber mixing completed from minutes to 1.5 h. The photooxidation of butyl iodine showed the presence of signals from reaction products and intermediaries for up to 50 h. Current detection limits of the chamber and analytical collection and testing approach were shown to be in the single-digit parts per billion levels. The comparisons between the measured oxidation trends and literature show the utility of performing laboratory experiments to validate the results of modeling for larger-scale scenarios. Researchers at Pacific Northwest National Laboratory constructed and tested an atmospheric chamber that begins to demonstrate the utility of such a chamber design for the study of the atmospheric fate of especially hazardous and radioactive gases.","PeriodicalId":19015,"journal":{"name":"MRS Advances","volume":"19 1","pages":"1097 - 1101"},"PeriodicalIF":0.8,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139296384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing electrocaloric ceramics could reach around 85% of the Carnot-limit, and existing electrocaloric polymers could enable a compact and high power density system. However, the performance of published system demonstrators stays significantly below this performance, partly because of the external electronic charging loss (cyclic charging/discharging of electrocaloric capacitors). This work analyzes how the latest 99.74% ultra-efficient power electronics enables to maintain a high performance even at the system level. A first-principle analysis on material and system parameters also shows the effect of significantly different material properties of ceramics (PMN, PST) and PVDF-based polymers on system parameters. A system benchmark provides insight into system characteristics not covered by material analysis.
