However, a critical challenge hindering their performance remains the quality of the perovskite emitting layer. Morphological and structural imperfections such as pinholes and halide vacancies, can significantly impede the subsequent layer deposition, leading to the formation of leakage current pathways. Furthermore, these lattice defects often serve as non-radiative recombination centers, compromising the device's overall luminescence efficiency. This study presents a facile strategy to address these limitations by incorporating polyethylene oxide (PEO) and trimethylolpropane triacrylate (TMPTA) as additives within the perovskite precursor solution. The high viscosity of PEO effectively restricts the diffusion of perovskite precursor, leading to the formation of smaller and more uniform crystal grains. In addition, the C=O functional group in TMPTA interacts favorably with uncoordinated Pb<sup>2+</sup> cations in perovskite, thereby suppressing non-radiative recombination processes. By meticulously optimizing the volume ratio of PEO and TMPTA additives, effective passivation of perovskite film defects and manipulation of crystal grain morphology are achieved, leading to a significant enhancement of the perovskite emitting layer quality. Consequently, the maximum current efficiency and external quantum efficiency of green light-emitting diodes reach 45.3 cd/A and 12.01 %, respectively. This work establishes a simple and effective methodology for fabricating efficient and stable PeLEDs.</div></div>","PeriodicalId":399,"journal":{"name":"Organic Electronics","volume":"142 ","pages":"Article 107249"},"PeriodicalIF":2.7,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739061","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}

The blended thin films are applied to phototransistor memory devices, with PPyMA as a photoactive electret and P3HT as a semiconductor channel. A comparative study of the two-transfer direction water side (forward structure) and air side (reverse structure) reveals that the vertical phase separation morphology of the aromatic side groups in PPyMA, along with its conjugation, is closely related to the photoresponse, memory retention, and durability of the photomemory devices. Electrical analysis shows that the device fabricated with the forward transfer (P3HT/PPyMA) can achieve photo writing through exposure to ultraviolet light at 265 nm, 310 nm, 365 nm, and blue light at 455 nm, while electrical erasure is performed via gate bias, resulting in a wide memory window (∼48.7 V). The device also exhibits a stable memory ratio in repeated write/erase measurements and long-term stability exceeding 10<sup>4</sup> s. In contrast, the device fabricated with the reverse transfer (PPyMA/P3HT), due to the reverse bilayer structure, required hole injection to pass through the insulating PPyMA layer, and holes may recombine with stored electrons during vertical transport, thereby dismissing the memory mechanism. As a result, the device cannot effectively store charges to achieve memory retention.
