摘要: Solution-processable graphene oxide (GO) ultrathin films were introduced as anode interfacial layers (AILs) for polymer solar cells (PSCs). The photovoltaic performance of PSCs containing thermal- and UV-treated GO was comparable to that with conventional poly(3,4-ethyledioxythiphene):poly(styrenesulfonate) AILs. UV treatment induced the surface activation GO; an increase in work function improved energy band alignment at GO/poly(3-hexylthiophene) interface, which accounted efficient hole collection treated GO.
