All spray pyrolysis deposited CdS sensitized ZnO films for quantum dot-sensitized solar cells

▶ Solar cells based on CdS quantum dot sensitized ZnO photoanode are fabricated. ▶ Both ZnO and CdS are prepared using ultrasonic spray pyrolysis technique. ▶ Good contact is formed between CdS and ZnO to facilitate the electron transfer. ▶ As-prepared cell achieves maximally a power conversion efficiency of 1.54%.
