However, their limited operational stability remains a key obstacle to commercialization. The hole transport layers (HTLs), PEDOT:PSS, and more recently, self-assembled molecules (SAMs), such as 2-(9H-carbazol-9-yl)ethyl phosphonic acid (2PACz), have shown promising performance. Nevertheless, using these HTLs individually is not ideal for the long-term stability of organic solar cells. In this study, we investigated the combination of these two well-established HTLs in a hole transport bilayer in PM6:Y6 OSCs. The PEDOT:PSS/2PACz bilayer is prepared using a simple two-step spin-coating process. This approach notably improves device reproducibility and, more importantly, reduces initial burn-in photodegradation, maintaining stable PCEs for over 650 h (27 days) of continuous illumination. In comparison, solar cells employing PEDOT:PSS or 2PACz as single HTLs retain only 80% of their initial PCE (t₈₀) after two and one day of illumination, respectively.

However, the intrinsic chirality polydispersity of synthetic SWCNTs leads to significant bandgap non-uniformity, which fundamentally limits the off-state performance and integration density of carbon nanotube thin-film transistors (CNT-TFTs). Here, we systematically investigate the influence of statistical bandgap distributions on the transport characteristics and leakage mechanisms of CNT-TFTs using three representative semiconducting SWCNT systems: single-chirality-enriched wide-bandgap (6,5) SWCNTs, mixed-chirality high-pressure carbon monoxide (HiPco) SWCNTs with an intermediate average bandgap, and mixed-chirality arc-discharge SWCNTs with a smaller average bandgap. We show that narrow-bandgap SWCNT networks exhibit higher on-state currents due to reduced Schottky barriers but suffer from pronounced band-to-band tunneling (BTBT) under high electric fields, resulting in degraded on/off ratios and subthreshold stability. In contrast, devices based on single-chirality-enriched (6,5) SWCNTs effectively suppress BTBT, maintaining ultra-low off-state currents (I_off &lt; 10⁻¹¹ A) and high on/off ratios (&gt;10⁶) even at high drain bias. These findings provide a material-selection guideline for carbon-based integrated circuits: wide-bandgap, single-chirality-enriched SWCNTs are advantageous for leakage-sensitive low-power logic applications, whereas mixed-chirality SWCNT networks with smaller average bandgaps are more suitable for high-drive-current analog and radio-frequency electronics.</p>","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 16","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70600","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
