Paper Abstract

In this letter, poly(methyl methacrylate) (PMMA), in which ZnCdS/ZnS core/shell QDs or ZnCdSe/ZnS core/shell QDs were embedded, was used to enhance the absorbance of light and, thereby, deliver power at greater efficiencies, as shown in Fig. 1. In order to attach QDs on the opposite side of an indium tin oxide (ITO)/glass substrate, a PMMA layer was used as a supporting material. The effects of the QDs + PMMA on the performance of the OPV cells are discussed. Furthermore, the dependence of the efficiency of the OPV cell on the photoluminescence wavelength of the core/shell QDs is discussed by comparing the two types of QDs.
