A novel efficient double junction InGaP/GaAs solar cell using a thin carbon nano tube layer

Using the two dimensional device simulator Silvaco Atlas, the photovoltaic characteristics of a double junction InGaP/GaAs solar cell [J.P. Dutta, et al., Optik. Int. J. Light Electron Opt. (2016)], were numerically simulated. In this work, the performance of double junction InGaP/GaAs solar cell is modified by adding a thin Carbon Nano tubes film. It was predicted that by adding a 110 nm thin carbon nano tubes film on the surface of the cell, the efficiency would be modified and would increase from 40.879% to 41.95%. Finally, the performances of the cell before and after the addition of the CNT thin film were compared.
