The performance and industrial viability of organic photovoltaics are stronglyinfluenced by the functionality and stability of interface layers. Many of theinterface materials most commonly used in the lab are limited in their operationalstability or their materials cost and are frequently not transferred towardlarge-scale production and industrial applications. In this work, an advancedaqueous-solution-processed cathode interface layer is demonstrated basedon cost-effective organosilica nanodots (OSiNDs) synthesized via a simpleone-step hydrothermal reaction. Compared to the interface layers optimizedfor inverted organic solar cells (i-OSCs), the OSiNDs cathode interlayer showsimproved charge carrier extraction and excellent operational stability forvarious model photoactive systems, achieving a remarkably high power conversionefficiency up to 17.15%. More importantly, the OSiNDs’ interlayer isextremely stable under thermal stress or photoillumination (UV and AM 1.5G)and undergoes no photochemical reaction with the photoactive materialsused. As a result, the operational stability of inverted OSCs under continuous1 sun illumination (AM 1.5G, 100 mW cm−2) is significantly improved byreplacing the commonly used ZnO interlayer with OSiND-based interfaces. |
