Abstract

We present a 2D Unified Solver for modeling metastability and reliability in solar cells. The current version of the solver is adopted to model carrier and defect transport in thin film photovoltaic devices. A unique feature of the solver is that defects transport, carrier generation and recombination mechanisms and grain boundary descriptions are treated on an equal footing. We propose and implement the standard implicit Euler method with Newton iteration for solving the reactions, which leads to improved accuracy and numerical stability. We use Gummel's method to solve a coupled set of reaction-diffusion-Poisson equations which has been discretized using the Scharfetter-Gummel scheme. We verify the solver on the test case of 2D chlorine anneal. We illustrate that process temperature profiles can be simulated as well.
