Zirconium Oxide Doped Organosilica Nanodots as Light‐ and Charge‐Management Cathode Interlayer for Highly Efficient and Stable Inverted Organic Solar Cells
Source abstract
Abstract
Abstract In this work, it is reported that zirconium oxide (ZrO2) doped organosilica nanodots (OSiNDs: ZrO2) with light‐ and charge‐management properties serve as efficient cathode interlayers for high‐efficiency inverted organic solar cells (i‐OSCs). ZrO2 doping effectively improves the light harvesting of the active layer, the physical contact between the active layer, as well as the electron collection property by habiting charge recombination loss. Consequently, all devices utilizing the OSiNDs: ZrO2 cathode interlayer exhibit enhanced power conversion efficiency (PCE). Specifically, i‐OSCs based on PM6:Y6 and PM6:BTP‐eC9 achieve remarkable PCEs of 17.16% and 18.43%, respectively. Furthermore, the PCE of device based on PM6:Y6 maintains over 97.2% of its original value following AM 1.5G illumination (including UV light) at 100 mW cm−2 for 600 min.
