However, achieving high luminance (≥ 100 lm/W), extended operational lifetimes (≥ 100,000 h), and cost-effective large-scale manufacturing remains a significant challenge. This review examines recent advancements in polymer-based WOLEDs, with a particular focus on semiconductor polymers as next-generation materials for achieving efficient white light emissions. Unlike traditional small-molecule WOLEDs, polymer-based systems offer solution-processable fabrication techniques, such as roll-to-roll printing and inkjet deposition, enabling scalable and cost-effective production. Key innovations discussed include thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) polymers, which enhance efficiency while maintaining spectral stability. Comparative analyses highlight how polymeric architectures can address color instability in multi-emitter systems and synthetic complexity in single-component emitters, positioning them as a more practical alternative for large-area applications. Furthermore, this review bridges the gap between laboratory-scale research and industrial commercialization, outlining strategies to improve charge transport, molecular stability, and device lifetime. Future research directions emphasize scalability, environmentally sustainable fabrication, and integration into next-generation lighting solutions. By evaluating the latest developments and identifying key challenges, this review provides a structured roadmap for advancing WOLED technology from experimental research to real-world applications. The insights presented herein hold global relevance for the advancement of sustainable energy solutions, aligning with international efforts to reduce carbon emissions and transition toward eco-friendly optoelectronic materials.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 9","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here in this report, we have successfully synthesized pure-phase crystalline Cu₂MnSnS₄ nanocrystals using the hot injection method which is further carefully characterized by various state-of-the-art techniques to investigate its structural, morphological, and optoelectronic properties. The high optical absorption and optimal band gap of 1.1 eV are observed, which is highly suited for solar cell applications. Furthermore, we pioneered the idea of fabricating the Cu₂MnSnS₄ nanocrystal-sensitized solar cell. We achieved a notable power conversion efficiency of 1.1% (~ fourfold higher) with n-CdS buffer layer than w/o n-CdS, 0.3%. The enhanced efficiency is directly attributed to the improved charge transfer and retard charge recombination across the p-Cu₂MnSnS₄/n-CdS interface. So far, to the best of our knowledge, we report the highest power conversion efficiency of 1.1% for Cu₂MnSnS₄ nanocrystals sensitized solar cell and energy band diagram for understanding the mechanism.

However, these approaches face limitations in achieving uniform and precise iodine incorporation. In this study, we propose an in situ iodine-doped sensitization process based on chemical bath deposition, offering a streamlined alternative. This one-step synthesis of iodine-doped PbSe films enables efficient sensitization, allowing for comprehensive control over dopant concentration. Systematic investigations reveal that iodine doping reduces the bandgap (from 0.317 eV to 0.303 eV), suppresses electron–hole recombination, and extends carrier lifetimes. At an optimal potassium iodide (KI) concentration of 1.8 × 10^–3 mol/L, the sensitized PbSe films exhibit a detectivity of 1.81 × 10⁹ Jones and a rapid response time of 1.97 ms under 1550 nm infrared illumination. Combined with X-ray photoelectron spectroscopy (XPS) and energy-dispersive spectroscopy (EDS) analyses, we demonstrate that iodine migration promotes lattice oxygen incorporation at grain boundaries, forming sensitization centers critical for enhanced photoconductivity.
