what the cheaper and easier to get is graphene to replace high cost, limited sources of material and high temperature difference between the ITO (indium tin oxide) electrode material as a quantum dot solar cells is the focus of this study. This study used a chemical vapor deposition (CVD) production of graphene electrode explore the relationship between the transmittance and the graphene sheet resistance graphene layers; then make a graphene material as an electrode of the solar cell devices of different size and detecting its performance, the conclusion that the material is graphene electrode PbSe / CdSe quantum dot battery, which can effectively improve the conversion rate of the quantum dot solar cells (up to 3.6%), and stability, but also can greatly reduce the cost;
