Fabrication and Simulating Solar Cell Devices using Silvaco TCAD Tools

Abstract

Solar cells are p-i-n photodiodes, which are operated under forward bias. The intention is to convert the incoming optical power into electrical power with maximum efficiency.

In this paper we are going to design a solar cell and simulation of solar cell using the Silvaco TCAD tools.

Silvaco TCAD refers to Technology Computer-Aided Design. This means that computer simulations are used to develop and optimize semiconductor processing technologies and devices. As TCAD simulations solve fundamental, physical partial differential equations, such as Poisson, Diffusion and Transport equations in a semiconductor device. This deep physical approach gives TCAD simulation predictive accuracy. It is therefore possible to substitute TCAD simulations for costly and time-consuming test wafer runs when developing and characterizing a new semiconductor device or technology.

Keywords- photodiode, Silvaco TCAD Tools.
