Large area graphene films were produced by chemical vapor deposition on copper foils and transferred onto glass as transparent electrodes. The hybrid solar cell devices consist of solutionprocessed poly (3,4-ethlene-dioxythiophene): poly (styrenesulfonate) (PEDOT: PSS), which is sandwiched between silicon wafer and graphene electrode. The solar cells based on graphene electrodes, especially those doped with HNO3, have comparable performance to the reference devices using commercial indium tin oxide (ITO). Our work suggests that graphene-based transparent electrode is a promising candidate to replace ITO.

Towards Flexible Transparent Electrodes Based on Carbon and Metallic Materials
Flexible transparent electrodes (FTEs) with high stability and scalability are in high demand for the extremely widespread applications in flexible optoelectronic devices. Traditionally, thin films of indium thin oxide (ITO) served the role of FTEs, but film brittleness and scarcity of materials limit its further application. This review provides a summary of recent advances in emerging transpa...
متن کاملAll-Carbon Electrodes for Flexible Solar Cells
Transparent electrodes based on carbon nanomaterials have recently emerged as new alternatives to indium tin oxide (ITO) or noble metal in organic photovoltaics (OPVs) due to their attractive advantages, such as long-term stability, environmental friendliness, high conductivity, and low cost. However, it is still a challenge to apply all-carbon electrodes in OPVs. Here, we report our efforts to...

متن کاملContinuous, highly flexible, and transparent graphene films by chemical vapor deposition for organic photovoltaics.
We report the implementation of continuous, highly flexible, and transparent graphene films obtained by chemical vapor deposition (CVD) as transparent conductive electrodes (TCE) in organic photovoltaic cells. Graphene films were synthesized by CVD, transferred to transparent substrates, and evaluated in organic solar cell heterojunctions (TCE/poly-3,4-ethylenedioxythiophene:poly styrenesulfona...
