Abstract
Additives treatment is a common way to improve the performance of dye sensitized solar cells. This project aims to investigate the performance improvement of DSSCs by treating Pt as a counter electrode and TiO2-mesoporous layer with Vanadium(V) oxide (V2O5-x). The electrical performance of the DSSCs show improvement and that was clear on their open-circuit voltage (Voc), short-circuit current density (Jsc), and overall efficiency (η). The calculation of power conversion efficiency (PCE %) is improved from 8.25 % without Vanadium(V) oxide (V2O5-x) to 9.10 % with the device treated TiO2-mesoporous layer with Vanadium(V) oxide (V2O5-x) and PCE 8.70 % with the device treated Pt with Vanadium(V) oxide (V2O5-x).
