An interface engineering process to deploy graphene film as the anode in poly(3-hexylthiophene-2,5-diyl):[6,6]-phenyl C61 butyric acid methyl ester (P3HT:PCBM)-based polymer solar cells is demonstrated. By modifying the interface between the graphene anode and the photoactive layer with MoO3 and poly(3,4-ethylenedioythiophene):poly(styrenesulfonate) (PEDOT:PSS), the power conversion efficiency of the solar cells reaches ˜83.3% of control devices that use an indium tin oxide (ITO) anode.

Diefeng Gu, Helmut Baumgart, Gon Namkoong New template based nanoelectrode arrays for organic/inorganic photovoltaic applications [Rapid Research Letter]
In this Letter the authors report a new nanofabrication technology to yield highly arrayed nanoelectrodes based on porous templates. This new process technology can significantly increase the space usage of porous templates. In addition, this novel nanofabrication technology allows for the optimal control of 3D parameters such as thickness, spacing, and height of nanoelectrodes, leading to maximum occupancy of organic photoactive materials between the nanoelectrodes. It provides a promising outlook for higher efficiency of hybrid organic–inorganic solar cells. phys. stat. sol.
