Bio-inspired optoelectronic devices, like nanocrystalline semiconductor-based dye-sensitized solar cells (DSSC) and organic solar cells (OSC) have attracted significant attention as a low cost alternative to conventional photovoltaic devices. However, further improvements are still necessary, and new materials need to be thoroughly explored, like the use new semiconductors materials. We demonstrate that DSSC devices constructed using titania-graphene paste thin films reach higher photocurrent and therefore higher efficiency than devices made with a commercial paste due to extra photocurrent generation.
