Enhancing photoelectrochemical performance through surface engineering of CdSe and Al-doped CdSe nanoparticles on ZnO/FTO photoanodes

The impact of a TiO2/r-GO composite material on the performance of electron transport electrodes of dye sensitized solar cells

“…A smaller contact angle means that dyes can cover the nanostructures more effectively, leading to enhanced photoconversion efficiency. 24 The X-ray photoelectron spectroscopy (XPS) technique was utilized to conduct elemental and chemical analyses of the In Fig. 4(a), a comprehensive analysis of TiO 2 /r-GO reveals the presence of four prominent peaks at binding energies of approximately 284.5, 458.3, 466.5 and 533.0 eV.…”
