Cadmium sulphide-sensitized zirconium dioxide (ZrO2) photoanode by successive ionic layer adsorption and reaction for solar cell application

Abstract In the present study, cadmium sulphide (CdS) quantum dot-sensitized ZrO 2 photoanodes have been analysed by using facial and cost-effective method, popularly known as successive ionic layer adsorption reaction (SILAR), performed at 300 K. The presence of compact ZnS treatment as-prepared photoanode is studied in this article to improve solar cell parameters. X-ray diffraction peaks infer nano-crystalline nature films with an average particle size 39.14 nm. CdS-sensitized show a significant increase absorption photons visible region (i.e., 200 520 nm) spectrum, we increased number SILAR cycles. Poly-sulphide electrolytes prepared double distilled water carbon black soot on conducting substrate used counter electrode be economical. J – V characteristic 10 CdS/ZrO TiO surface passivation (ZnS) gives maximum sc 1.46 mA/cm fill factor 0.34 conversion efficiency 0.46%. Electrochemical impedance spectroscopy understand kinetics charge transfer transport processes mechanisms involved.
