By incorporating low weight percentages of graphene in our precursor solution and using a technique derived from spray pyrolysis, we obtained a low cost TCO with excellent properties, characterized by AFM, UV-VIS and Hall Effect. The film roughness was calculated to be ~7.49-12.7 nm, while band gap was determined to be ~4.0-4.2 eV. The material’s optical transparency ranges from 84-86% and its resistivity was measured to be ~5.5-8.5 x10-3 Ω cm. With these results, we suggest that the obtained material is a proper candidate for use in photovoltaic applications, such as Grätzel solar cells, which will be our main focus.
