Titanium dioxide particles were added to the texture of polypyrrole nanoparticles as the filler in order to increase electron transfer in the active layer of the solar cell. Polypyrrole nanoparticles were electrochemically synthesized in the shortest time possible with an ideal morphology and a particle size of less than 40 nm using a new multi-step amperometry technique. The results of EDAX analysis confirmed the existence of titanium particles in the texture of polypyrrole. The crystal size was determined through XRD analysis. SEM images confirmed the uniform and spherical appearance of polypyrrole nanoparticles with spongy and porous structures. Based on the results, the increase in the efficiency of the prepared solar cell based on polypyrrole/TiO2 nanocomposite coated on the copper surface (compared to common polymeric solar cells) was 39.7%. Application of copper as the conductive metal surface improves the electrical conductivity .
