Özet
Developing efficient and cost effective photoanode and counter electro materials have been a persistent objective by a wide community for efficient, cost effective and stable dye-sensitized-solar cells (DSSCs). We have developed a unique and inexpensive way of co-electroplating-annealing method to synthesize metal oxides and employed it to prepare ZnO material on top of doctor bladed TiO2 as photoanode and CuO on top of reduced graphene oxide (RGO) as counter electrode. By sandwiching these two electrodes with I-/I3 redox couple in-between we have shown the improvement of photovoltaic properties with ZnO barrier layer using Pt or cost effective CuO/RGO counter electrodes (CEs). This paper provides a comprehensive guide to prepare those electrodes cost effectively and fabricate metal oxide sandwiched DSSCs providing up to 6.91% power conversion efficiency with 26.5% enhancement compared to the conventional DSSCs with TiO2 photoanode and Pt CE under AM1.5 simulated solar light. This work also addresses the reduction of fabrication cost of the cells to make them more economically viable as it is
