Abstract: Systems, methods and devices for the efficient photocurrent generation in single- or multi-walled carbon nanotubes, which includes (SWNTs)/poly [3-hexylthiophene-2,5-diyl] (P3HT) hybrid photovoltaics, and exhibit the following features: photocurrent measurement at individual SWNT/P3HT heterojunctions indicate that both semiconducting (s-) and metallic (m-) SWNTs function as excellent hole acceptors; electrical transport and gate voltage dependent photocurrent indicate that P3HT p-dopes both s-SWNT and m-SWNT, and exciton dissociation is driven by a built-in voltage at the heterojunction. Some embodiments include a mm2 scale SWNT/P3HT bilayer hybrid photovoltaics using horizontally aligned SWNT arrays, which exhibit greater than 90% effective external quantum efficiency, among other things, which advantageously provide carbon nanomaterial based low cost and high efficiency hybrid photovoltaics.
