Achieving high mobility is crucial for maximizing the efficiency of these devices. Titanium dioxide (TiO<sub>2</sub>) is widely used as an ETL due to its affordability, stability, and ease of fabrication, despite limitations such as low conductivity, mismatched conduction bands with perovskite layers, and susceptibility to surface defects under ultraviolet light. To address these challenges, doping TiO<sub>2</sub> with several metal ions has emerged as a promising strategy to improve its electrical and optical characteristics. This review emphasizes on the bulk alteration of the TiO<sub>2</sub> layer via metal ion doping, aiming to enhance charge carrier density, optimize band alignments, and mitigate interfacial recombination. Moreover, understanding the mechanisms by which doping modifies these properties is critical for guiding future research efforts. Metals like Sn, Fe, Ru, and Nb and non-metals (S) have shown potential to enhance TiO<sub>2</sub> performance by increasing conductivity and reducing energy losses. Future research should explore optimized doping concentrations and novel dopants to further enhance the power conversion efficiency (PCE) and long-term reliability of TiO<sub>2</sub>-based PSCs, contributing to the advancement of efficient solar energy technologies.

Mostly dissimilar weld joints offer an excellent combination of attractive properties, such as strength, hardness and corrosion resistance at lower costs. In the present study, dissimilar welded joints of 316L austenitic stainless steel (ASS) and 410 martensitic stainless steel (MSS) were investigated using both pulsed tungsten inert gas (PTIG) and gas tungsten arc welding (GTAW) techniques. The base metal of 316L ASS exhibited mainly austenitic grains, while the 410 MSS base metal displayed mainly martensitic microstructure. The fusion zone of the PTIG weldment showed austenitic grains and exhibited a martensite phase with precipitated carbide particles in the weld zone. The highest hardness was noted in the heat-affected zone (HAZ) of 410 SS grade (~254HV) as compared to 316L SS grade at HAZ (~168 HV) using GTAW. The PTIG weldment revealed higher toughness (~76 J) compared to GTAW (~62 J). Potentiodynamic polarization studies showed noble pitting potential (–0.251mV) for PTIG-welded joints as compared to GTAW-welded joints (–0.421mV). In comparison to GTAW-welded joints (17.264 × 10<sup>–5</sup> µA cm<sup>–2</sup>), PTIG-welded joints had a significantly lower corrosion current density (0.46 × 10<sup>–5</sup> µA cm<sup>–2</sup>), indicating higher corrosion resistance. The improved mechanical and better corrosion properties in PTIG-welded joints attributed to the controlled heat input due to the pulsing effect, which has resulted in less distorted microstructure and narrower heat-affected zone, and low chromium carbide precipitation around the welded joints, which helps in retaining the uniformity in the alloying element across the matrix.</p></div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"49 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147339317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
