Abstract

Nowadays, the development of optical systems applied to the generation of clean and renewable energy is one of the great challenges of the 21st century. This work presents a theoretical and experimental study of shrinkage in multiplexed holographic lenses (MHL) stored in a low-toxicity photopolymer named Biophotopol. For this purpose, a study has been carried out using k-space tools. In addition, a study has been performed to optimize the number of MHLs, the hologram thickness, and the angular distance between peaks. To evaluate the efficiency, the short-circuit current has been evaluated under solar illumination with different incident reconstruction angles.
