Modeling and design of graphene /GaAs solar cell.

Abstract

The discovery of Graphene has allowed researchers to access a whole new world, the 2D Materials world. Since its discovery in 2004, many researches have been done to study its properties and how it can contribute to more than Moore microelectronics, above its very promising properties in PV solar cells. In this thesis, we have tried to remake a study that was done in late 2014 by Yawei Kuang and Yushen Liu from the School of Physics and Electronic Engineering, in Changshu Institute of Technology, China, where a Graphene/GaAs Schottky Junction Solar Cell was modeled and designed using SILVACO ATLAS (TCAD) simulation tool. We have developed our own SILVACO ATLAS (TCAD) simulation program. Simulations were done under AM1.5 illumination, with different GaAs substrate thicknesses and different n-type doping concentrations, allowing us to obtain efficiencies near 9.54%.
