Optimizing 1D Photonic Crystal Structures for Thin Film Solar Cells

The work implemented in this paper is toward the optimization of distributed Bragg reflectors (DBRs) as a 1D photonic crystal structure. These DBRs showed significant potential in various optical applications based on the existence of a tunable photonic band-gap. Herein, the utilization of the DBRs in thin film solar cells (TFSCs) were addressed showing its impact as a back reflector structure. Optimized DBR structure, with respect to the number of layers, material selection and layers thickness, was simulated and validated with previously published experimental and numerical results.
