Claim Text:
1. An organic or organic/inorganic hybrid photovoltaic conversion device comprising: a composite film of a photoactive polymer, fullerene C an electrode adapted to collect current; wherein the composite film has a surface roughness, Ra, of 8.33 nm; wherein upon light irradiation of the composite film, photo-induced charge separation at the polymer:fullerene C wherein the photoactive polymer, the fullerene C wherein the photoactive layer defines a first plane; wherein the carbon nanotubes are oriented in a direction that is perpendicular relative to the first plane; wherein the photovoltaic conversion device has a short-circuit current density of 2.52 mA cm wherein quantum dots are dispersed in the photoactive polymer; and wherein the absorption spectra of the quantum dots and the photoactive polymer are complementary.
