Abstract

The interface layer greatly affects the performance of organic solar cells (OSCs). In this paper, we selected an amino-containing silane molecule (AEEA) and four fluorescein molecules with different functional groups to prepare a series of cathode interface materials based on organosilica nanodots (OSiNDs) by one-step hydrothermal synthesis, in order to research the impact of functional groups on the performance of OSC devices. The good film crystallinity and carrier mobility without high-temperature annealing endowed the OSCs with high Voc and Jsc, and the best efficiency of 15.91% was reached with the OSi-ErB cathode interlayer. Moreover, compared with ZnO devices, OSiND-based devices showed highly improved light stability after UV irradiation.
