Cathode interface layer based on organosilica nanodots for stabilized inverted organic solar cells
摘要
In this work, we used three amino-containing silane molecules (APTMS, DAMO, AEEA) to synthesis organosilicon nanodots (OSiNDs-AP, OSiNDs-DA, and OSiNDs-AE) by one-step hydrothermal, respectively. The OSiNDs were used as cathode interlayer (CIL) in organic solar cells (OSCs). The OSiNDs-AE decreased the work function of ITO cathode and enhanced the charge carrier extraction without high-temperature annealing, resulting higher devices performance (PCE = 15.45%). Meanwhile, the OSiNDs-AE based OSCs with PM6:Y6 exhibited highly improved light stability compared with the device based on ZnO CIL.
