Research Overview

stability, organic photovoltaics, nonfullerene acceptors, small molecular, all-polymer, vertical phase separation, interfacial engineering


Organic photovoltaics (OPVs) have developed rapidly, among which power conversion efficiency (PCE)  exceeds 18%. However, the stability study including thermal stability, photo-stability, photochemical stability, etc. on OPVs is still lagging behind. My work is to explore and improve the stablity of different blend systems-based OPVs, thereby extending their operional time which will be benefitial for their commercialisation.
