Abstract
For the first time, bismuth oxide (Bi2O3) nanoplates synthesized by single-step chemical methodwere envisaged as photoanodes in dye-sensitized solar cells. The structural elucidation demonstratedtetragonal structure with a predominant β-Bi2O3. The power conversion efficiency (1%) of Bi2O3nanoplates-based dye-sensitized solar cells was enhanced up to 50% when decorated with zinc oxidethin layer (ZnO). The best performing electrode showed 24% incident photon-to-current conversion effi-ciency. This high DSSC performance of Bi2O3-ZnO photoanode is attributed to the increased electrontransportation due to the suppression of recombination centers by ZnO passivation layer.
