Abstract

In an effort to find an alternative way of incorporating quantum dot (QD) based luminescent down-shifting (LDS) films into photovoltaic (PV) devices, transparent (at long wavelength) zinc oxide (ZnO) films have been grown by chemical bath deposition (CBD) to form novel encapsulation matrices for QD based LDS films. The ZnO films appear to be stoichiometric (Zn:O) and meso-porous as characterised by energy dispersive x-ray analysis and scanning electron microscopy. QDs have been loaded into the films for varying lengths of time (24–72 h) resulting in measureable fluorescence upon excitation with a blue LED.
