Summary:We have demonstrated an architecture of polymer solar cells based on allotropes of nanocarbon materials which can be fabricated fully compatible with solution processed printable electronics. The device consists of a transparent conducting electrode using one-dimensional (1D) single-walled carbon nanotubes (SWNTs), a hole transporting interfacial layer using two-dimensional (2D) graphene oxide (GO) and the zero-dimension (0D) fullerene derivative phenyl-C61-butyric acid methyl ester (PCBM)/poly(3-hexylthiophene) (P3HT) blends as a photoactive layer. A promising power conversion efficiency of 3.1% can be achieved in this nanocarbon based polymer solar cell. The fully solution processable SWNT/GO anode can be a good candidate to replace the traditional transparent conducting electrode ITO and the interfacial anode layer PEDOT:PSS, providing a new route to develop low-cost, large area and flexible organic photovoltaic devices based on the nanocarbon platform.
