ABSTRACT

Dye-sensitized solar cells (DSSCs) offer several advantages over traditional silicon semiconductor solar cells, including simple manufacturing processes, low cost, stable performance, and the potential for large-scale production. Graphene, known for its excellent electron transport properties and long electron lifetimes, is an ideal choice as a photoanode composite material. Graphene possesses high electrical conductivity, thermal stability, and a high specific surface area. It also has the lowest known electrical resistivity. In this study, DSSCs were fabricated using the doctor blade method by incorporating different concentrations of single-layer graphene into titanium dioxide (TiO2). Then, the effects of various graphene concentrations on the performance of DSSCs were investigated. The addition of graphene, with its unique properties, influenced the efficiency, stability, and overall performance of DSSCs. By optimizing the concentration of graphene, the photovoltaic properties were enhanced which allows for various applications of these solar cells in various energy solutions.
Keywords: Dye-sensitized solar cells, Carbon nanotubes, Multi-walled carbon nanotubes, Titanium dioxide (TiO2)
