Model-order reduction (MOR) is a numerical approach that has been successfully applied across many disciplines to obtain computationally efficient reduced-order models (ROMs). Despite these successes and the potential to avoid physical assumptions and approximations, MOR has not yet been explored for the development of compact photocurrent models, where traditional analytic techniques dominate. In this article, we demonstrate the viability of MOR in this context by using proper orthogonal decomposition to develop a hybrid analytic-numerical compact model, which replaces analytic solutions of the ambipolar diffusion equation with numerical ROM solutions. We demonstrate our model by comparing its predictions with those of a state-of-the-art analytic model using photocurrent measurements obtained at the Little Mountain Test Facility.
