Organic Photovoltaic Device Model is a 1D Schottky-Read-Hall based drift diffusion model specifically designed to model organic photovoltaic (OPV) devices. It can describe non-geminate recombination via two mechanisms: free-to-trap processes via an exponential tail of trap states, and free-to-free carrier processes. The model solves the drift diffusion equations for electrons and holes, Poisson's equation to calculate the potential distribution in position space, and the Schottky-Read-Hall capture escape equations for a discretized set of energy levels. The model has been used to generate a number of publications. It can simulate the following experiments often used to characterize OPV devices: JV curves (Light/Dark), Charge extraction data (Light/Dark), and Steady state recombination data (Light/Dark).
