Photonic nanometer scale metamaterials and nanoporous thermoelectric materials for enhancement of hybrid photovoltaic thermoelectric devices

摘要

This paper discusses the design, development and implementation of a plasmonic fishnet meta-structure, synthesis of TE ink and binder, fabrication of conductive ink, and printing technology to improve the overall efficiency of the hybrid PV-TE devices. Embedded fishnet meta-structure in hybrid photovoltaic-thermoelectric (PV-TE) system and, synthesis/characterization of printable nanoporous thermoelectric (TE) ink are proposed. Back passivation layer of the solar cell includes a planar fishnet structure that enhances solar radiation absorption near the infrared band of the solar spectrum. It was observed to improve the efficiency around 11 folds in the hybrid system with fishnet. Nanoporous Bi2Te3 and Sb2Te3 were used to prepare printing inks to print p-n junctions. Development of fishnet, synthesis/characterization of TB ink, binder and conductive ink are elucidated in this paper. (C) 2015 Elsevier B.V. All rights reserved.
