Factors such as crystallinity, morphology, phase formation, light absorption, and surface chemical state of rGO-TiO2 were investigated. As a result, functional groups or chemical states revealed the presence of Ti-O-C in rGO-TiO2 nanocomposite after the sputtering process. The titanium source from the target was of Ti3+ species as determined using X-ray photoelectron spectroscopy (XPS). It was found that average sized Ti3+ ions of around 59.4 nm were incorporated into the rGO nanosheet. A customized Dye-Sensitized Solar Cells (DSSCs)device was fabricated with the photo-anode consisting of sputtered rGO-TiO2 nanocomposite. After optimization, the Ti target allocated with 10 cm-apart FTO glass-coated rGO nanosheet and 0.67 cm2 active area exhibited an ideal PCE of 6.60%, which is remarkably higher than the usual 5 cm sputtering distance the sample (1.90%)had achieved. � 2019 Final 2023-05-29T07:24:26Z 2023-05-29T07:24:26Z 2019 Article 10.1016/j.solener.2019.05.069 2-s2.0-85066259028 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85066259028&doi=10.1016%2fj.solener.2019.05.069&partnerID=40&md5=31ec6fe9dec0e81296b73d8c0bef2264 https://irepository.uniten.edu.my/handle/123456789/24546 188 10 18 Elsevier Ltd Scopus |
