Carbon nanotube hybrid photovoltaics

摘要: 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, exhibit following features: measurement at individual SWNT/P3HT heterojunctions indicate that both semiconducting (s-) metallic (m-) SWNTs function as excellent hole acceptors; electrical transport gate voltage dependent P3HT p-dopes s-SWNT m-SWNT, exciton dissociation is driven by a built-in heterojunction. Some embodiments include mm2 scale bilayer photovoltaics using horizontally aligned SWNT arrays, greater than 90% effective external quantum efficiency, among other things, advantageously provide nanomaterial based low cost high efficiency photovoltaics.
