Optical and thermal analysis of PVB encapsulant polymer doped with yellow 083 and orange 240 organic dyes for photovoltaic application

This work described a process based on the luminescent down shift (LDS) technique, in order to introduce the luminescent organic dye into PVB polymer encapsulant as emergent material 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 two organic dyes yellow 083 and orange 240 in ethanol solvent. The methodology and experimental conditions such as laboratory polymer preparation and analysis were presented. The absorption spectrum of the prepared PVB material shifts towards longer wavelengths, with increasing organic dye concentration.
