N2 - The application of luminescentdown-shifting (LDS) has been shown to improve the short wavelength response of a variety of different photovoltaic devices. Cadmium sulphide/cadmium telluride (CdS/CdTe) heterojunction devices possess a great potential for improvement via LDS due to the parasitic absorption of blue light by the CdS buffer layer. This work is the first to investigate LDS applied to mini-modules (72 cm2 active area) cut from full-size CdTemodules from a productionline. The addition of LDS layers containing Lumogen Yellow 083 and Violet 570 dyes was demonstrated to increase the shortcircuitcurrentdensity (JSC) of the mini-module by up to 9% relative. It was shown that the addition of the Yellow 083 dye alone more than doubles the short wavelength (300–500 nm) response of CdTemini-modules. External quantum efficiency measurements are presented that clearly identified the wavelength range of photocurrent enhancement, while increased efficiency was confirmed with current–voltage (I–V) measurements.
