Abstract

In Dye-Sensitized Solar Cells (DSSC), the platinum -free counter electrode has its own charm. Copper selenide and lead sulphide thin films are tried as substitutes for the platinum electrode in this work. These materials were prepared by the Chemical Bath Deposition technique (CBD) and their structural, compositional and electrical properties were studied in detail. DSSC was fabricated using natural dye from pomegranate as the photosensitizer. The photovoltaic performance of DSSC was evaluated with the two alternate counter electrodes and compared with the conventional platinum electrode. Results show that DSSC using copper selenide electrode exhibits appreciable power conversion efficiency when compared to platinum electrode under similar conditions.
