Organic photovoltaic cell with 17 percent efficiency and superior processability for large-area coating

Organic photovoltaic cell with 17 percent efficiency and superior processability for large-area coating

Organic photovoltaic (OPV) cells have attracted considerable research interest because of advantages of lightweight, flexibility and low-cost solution processing. With the development of organic photoactive materials, especially the new-emerging non-fullerene electron acceptors (NFAs), OPV cells have yielded power conversion efficiencies (PCEs) of over 16% in recent years. However, these devices were usually fabricated by spin-coating […]
