Automatic optimization of solar cells with spatially varied absorber's band-gap

摘要

We developed a numerical procedure, based on Nelder-Mead simplex optimization algorithm, which, by optimizing an objective function, shapes the solar cell absorber's band-gap profile. The minimization of the thermalization power loss and the heat power loss is investigated in order to obtain solar cell with the overall maximum open-circuit voltage and/or maximum output power.
