Encapsulant polymer materials functionalized by luminescent down shift technique (LDS) with metallic oxides for photovoltaic application

摘要

This work focused on the technology of luminescent down shift (LDS), with a primary aim to identify and investigate a methodology to introduce the metallic oxides as inorganic luminescent materials into EVA and PVB polymer encapsulant as emergent materials for photovoltaic application. For this goal, we propose to study the feasibility to implement the LDS functionality and to identify suitability of available luminescent to be incorporated into the host polymer encapsulant material. The first step to this direction was through a comprehensive optical study of metallic oxides nanoparticles in organic solvent. The methodology and experimental conditions such as laboratory polymer preparation and luminescence dye concentration were presented. Also, the emergent polymer encapsulant sheets were characterized by using optical analysis techniques. The absorption spectrum of the prepared PVB material shifts towards longer wavelengths, with increasing metallic oxides concentration.
