Abstract :
We present a photoluminescence study of a high-throughput experiment in which nanocrystal inks of different composition are mixed to produce a continuous composition gradient. Using this technique we have produced films in which the cation ratios of a CZTSSe absorber layer are continuously varied laterally on the substrate. Here we report the compositional dependence of peak intensity, position, and peak shift with intensity as a function of composition.
