제목 Solution-Processed Interlayer based on Nematic Derivatives for Organic Photovoltaic Devices: Enhancement of Ordered Orientation and Crosslinking Adhesion
초록 Organic photovoltaic cells (OPVs) have drawn significant attention for these applications due to the global technology trends toward economic feasibility and continuous development coupled with efforts to preserve the environment. To improve the charge transport between the interfaces, a number of investigations to study the effects of introducing an interlayer have been reported recently. In particular, most research efforts have focused on the use of alcohol/water-soluble conjugated polymer electrolytes (CPEs) for the interlayer. In this study, we synthesized alcohol/water-soluble small molecules with n-type backbones. We introduced various nematic molecules into the backbone to achieve effective charge transfer between the interfaces and ordered orientation. Due to the effective charge transfer and ordered orientation, improved FF, JSC, VOC and PCE values are expected in these OPVs.
