Over the past one decade, progresses in nanoscience and nano technology have unlocked up novel avenues for the formation of operative photo cells. Currently, metal, polymer and semiconductor nanostructure designs for photovolotaic cells can be built. Considering the optical and electrical mechanisms underlying photovoltaic conversion has also helped from hypothetical and modeling reviews. The great cost and low efficacy of contemporary solar photo voltaic cells avoid solar energy from being used extensively. nanomaterials of one-dimensional (1-D) in particular have made original project potentials for additional efficient solar cells possible because of nanostructured ingredients. These one-dimensional nano structures, which include nanowires, nanorods, and nanotubes, present fantastic opportunities to boost photon concentration, electron transport, and electron gathering in photovoltaic battery. Graphene is a 2D (two-dimension), atomically thin, hexagonal lattice of carbon. The noteworthy automatic characteristics of graphene are attributed to its organization, where every three of its four negative charged particles in covalent connections of carbon atom bonds by its closest neighbors (sp2 bonds). Meanwhile, the material's optoelectronic capabilities are mostly attributed to the left over charge in fourth position, which delocalize throughout the two-dimensional frame. Moreover, it is well known that graphene is more mobile than superior metals. Furthermore, since thin films of graphene may stand created via a number of solution-based approaches, including basic spin coating, a wide range of compositions can be produced utilizing inexpensive, simple, and large-scale procedures. In this study, a solar cell in 2D with graphene is modeled and examined using the finite element method.
