Abstract
We present a Bloch modes-based Green’s function scattering formalism for cost-efficient forward modeling of disordered binary surface textures. The usage of Bloch modes of an unperturbed reference ordered system as an ansatz allows our formalism to address surface scattering beyond the shallow amplitude regime. The main advantage of our formalism is the possibility to utilize a small amount of plane waves to represent the assumed Bloch modes thereby reducing computational costs, while still allowing one to estimate the scattering response to all channels accessible by the disordered system. Benchmarking calculations discussed in the paper demonstrate how the usage of our Bloch modes ansatz provides an excellent estimate of the scattering response over an important regime of disorder. As an example of our method’s strength, we examine an electrically decoupled binary light trapping texture and demonstrate how introducing disorder may improve light in-coupling into the considered solar cell structure.
