Spectral control in thermophotovoltaic systems by optimized one-dimensional photonic crystals

摘要

We report computational results on the optical response of quarter-wave periodic, modified periodic and optimized photonic crystals based on Ge and MgF2 materials. Transfer matrix method and pattern-search optimization algorithm have been combined to achieve high performance structures destined to spectral control in thermophotovoltaic systems. Our computations demonstrate that the pattern-search algorithm is readily applicable to optimal design of photonic crystals within reduced computing time. High optical performance and spectral efficiency have been achieved. (C) 2017 Elsevier GmbH. All rights reserved.
