- Abstract
One dimensional (1‐D) CdS nanowires have been grown through a low temperature chemical route and have been sensitized with eosin‐G and ethyl eosin dyes to broaden the absorption spectrum of CdS and to enhance the photoelectrochemical (PEC) performance under illumination. The used method is advantageous due to its simplicity, low cost, scalability, and controllability. Interestingly, eosin‐G and ethyl eosin dyes yield nearly four‐ and six‐fold increase in device efficiency compared to bare CdS when tested in dye‐sensitized solar cell assembly. Structural, surface morphological, optical, and surface wettability studies have been formulated for CdS, whereas identification of materials along with PEC investigations were conducted through current density–voltage (J‐V), external quantum efficiency (EQE), characteristics under the illumination of 94.6 mW/cm2 (AM 1.5G), and electrochemical impedance spectroscopy (EIS).
