"charge transport properties OTFTs Y6... non-fullerene acceptor (NFA)...  enhancement power conversion efficiency organic solar cells... increase mobility lowered temperatures... band-like transport... band-like transport originates from the unique molecule packing motif of Y6 and the special phase of the film. Their work not only demonstrates the superior charge transport property of Y6, but also suggests the great potential of developing high-mobility n-type organic semiconductors and TFTs on the basis of Y6"
