Study on the Silicon based Hetero-Junction Structure Solar Cell by using Silvaco TCAD / Azaryna Noh

In this paper, the study on the silicon based hetero-j unction stnicture solar cell using Silvaco software packages has been demonstrated. In this study, hetero-j unction of nGaAs/n-Si/p-Si, n-AlGaAs/n-Si/p-Si, n-InP/n-Si/p-Si, and n-InGaAs/n-Si/p-Si solar cells were simulated. Firstly, fundamentals of solar cell operation, performance and designs issues have been presented. The simulation of the solar cells using Silvaco TCAD Tools consisted of processes simulation of constructing solar devices in ATHENA and simulation of electrical characteristics of solar devices in ATLAS. The results from all simulations of the hetero-junction of solar cells were analyzed to compare their performances. Then, the paper was concluded with an argument that the hetero-junction of n-GaAs/n-Si/p-Si solar cell would provide better performance and efficiency over the others heterojunction solar cells. Finally, the future design improvements have been suggested.
