In order to increase the use of solar energy, which is one of the renewable energy sources, it is to produce high-efficiency, low-cost and environmentally friendly dye-sensitive solar cells from solar cells provided by photovoltaic technology that generates electricity from solar energy. Therefore, there is a need to develop new materials and modified designs to produce solar cells at lower cost. One way to increase the efficiency of dye-sensitized solar cells (DSCC) is by doping at the anode. At the same time, graphene paste was used instead of Pt cathode to reduce the cost. In this study, pure and Cobalt (Co+2) added TiO2 pastes were prepared to produce DSCC. Photovoltaic performances were determined by comparing pure and doped batteries with each other. For this purpose, pure and Co+2 added TiO2 pastes were first prepared. The resulting pastes were applied to FTO glasses with the doctor-blade method. Then, DSCCs were produced by sandwiching pure and Co+2 doped TiO2 photoanodes sensitized with N-719 dye with graphenecoated FTO thin films. The performance of the produced DSCCs was determined by Current Density (J) - Voltage (V) analysis. There was a certain increase in FF and Jsc values with doping. However, the results showed that the efficiency value of Co+2 doped batteries is 370% above the value of batteries using pure TiO2 photo-anodes.
