Abstract

To demonstrate the potential for building integrated photovoltaics (BIPV) incorporation of thin-film photovoltaics, commercially available quantum dots (QDs) have been deposited, as part of a poly(methyl methacrylate) (PMMA) composite film, on a cadmium telluride (CdTe) micro-module. This resulted in an increase in photocurrent generation through the luminescent down-shifting (LDS) process. The optical properties of these films were characterized through UV–vis spectroscopy. The impact of the film on the micro-module was studied through current–voltage (I–V) and external quantum efficiency measurements. Further layers were added to the initial single-layer LDS film, however no additional improvement to the micro-module were observed. Additionally, a range of emission wavelengths have been explored. The majority of these films, when tested on a CdTe device, were shown to improve the photocurrent generation whilst also visually displaying the vivid colour palette provided by quantum confined materials. The future feasibility of using QD based LDS films for large scale BIPV-based power generation has also been discussed.
