Full Title: Modeling of P-N Junction Devices using Various Materials for Photovoltaic Applications Under Different Operating Environments
Photovoltaic devices are typically two-, three- or multi-layer junction devices which can generate carriers on exposure to photon radiation. There are several essential device-specific factors and parameters which are required for accurate modeling and simulation of such devices. In this talk, Dr. Roy will talk about a tool called ADEPT (A Device Emulation Program and Tool) on nanoHUB for modeling and simulating photovoltaic devices using a range of different materials and structural configurations. ADEPT is a detailed numerical device simulation code developed at Purdue University. In this tool, semiconductor equations, Poisson’s equation, and the hole and electron continuity equations (assuming drift-diffusion transport), are solved numerically, subject to appropriate boundary conditions (typically an ideal ohmic contact). Dr. Roy will describe how to model a simple silicon-based solar cell and then go over simulating photovoltaic devices composed of various other materials. In addition, it is very important to obtain the material-specific electronic and optical properties before we can start simulating our device models. In this regard, Dr. Roy will briefly talk about some other tools and software which can be used to obtain the electronic and optical properties of materials to be used in photovoltaic applications. Specifically, he will talk about Quantum ESPRESSO for calculating electronic and optical properties of materials, and Stanford Stratified Structure Solver (S4) for modeling optical features of multi-layer devices.
