  "abstract": "This work assembled dye solar cells by replacing platinum with graphite on indium tin oxide (ITO). First, the device was tested only on the ITO; afterward, graphite was placed on the ITO and evaluated as a counter electrode in the cell. The results showed that the presence of graphite increased the incident photocurrent conversion (IPCE) of the cell. The electrode used was a combination of zinc oxide with 4% bismuth, and characterization of the film had high reflectance in the visible region, a thickness of around 1.47 μm, and a crystallite size of around 38.5 nm. The addition of graphite as a counter electrode increased the cell efficiency by 10 times, driven by an increase in current density from 0.02 to 1.2 mA/cm and in IPCE from 0.04 to 2.26%.",
