Recently, research on composite nanofilms has progressed in pursuit of further enhancing these properties. This paper reports a crossed-spray deposition method to implement it using two atomizers. With the crossed sprays of hole transport layers (HTL) and photoactive layers (PL), the structured nanofilms with multiple components were produced with a higher electrical conductivity and optical absorptance than that formed by a single spray only. The experimental results showed that an organic solar cell comprising the HTL and PL from the crossed sprays was produced with better performances than the single spray.

The findings reveal that all Cr coatings deposited by HiPIMS exhibit a (200) crystal plane preferential growth. Cr coatings deposited with narrow pulse widths possess dense structures with minimal columnar growth. As pulse width increases, the fiber texture of the coating becomes more pronounced, leading to a gradual decrease in hardness and scratch resistance. During steam oxidation at 1200 °C, Cr coatings deposited with wider pulse widths facilitate O diffusion due to enhanced columnar growth. This results in complete oxidation at an early stage, forming a dense oxide layer that impedes further inward O diffusion and outward Zr diffusion. In contrast, Cr coatings deposited with narrower pulse widths effectively slow down internal O diffusion owing to their denser structure. Consequently, a dense oxide layer forms on the surface, further restricting oxygen ingress. However, the remaining Cr layer fails to prevent the outward diffusion of Zr, resulting in the formation of ZrO<sub>2</sub> channels in a lattice pattern, which exacerbates the oxidation of the Zr substrate.</div></div>","PeriodicalId":23182,"journal":{"name":"Thin Solid Films","volume":"814 ","pages":"Article 140626"},"PeriodicalIF":2.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422701","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}
