In this paper, the optimization, elaboration and characterization of an efficient spectral beam
splitter based on a simple RF sputtered ITO/Ag/ITO (IAI) ultra-thin multilayer structure are
presented. An experimental investigation assisted by Genetic Algorithm (GA) metaheuristic
optimization was carried out to achieve high-performance spectral splitter for tandem solar
cell applications. The RF magnetron sputtering method was used to elaborate the optimized
IAI structure. The optical and structural properties of the sputtered splitter were also analyzed …
