Analytical Modeling of Industrial-Related Silicon Solar Cells

Abstract

Fast and accurate simulation tools are key to increasing our understanding of silicon-based solar cells. A lucid graphical unit interface and experimentally obtained input parameters help make these tools accessible for a wide range of users. In this paper, we present a fast Excel tool based on the well-known two-diode model supporting conventional and metal-wrap-through cell architectures. The selective emitter approach, spatial varying emitter recombination, and optical simulations are taken into account. A set of consistent input parameters, including the emitter recombination in the passivated case, as well as the metal contacted for both idealities, are given as a function of the emitter sheet resistance. This set on input parameters is associated with industrial-related technologies for conventional and metal-wrap-through silicon solar cells.
