Abstract
Photovoltaic (PV) response of hybrid organic/inorganic bilayer heterostructures based on organic polymers or small molecules on the one hand, such as poly(3‐hexylthiophene), polyaniline doped with poly(styrenesulfonic acid), poly(ethylene‐3,4‐dioxythiophene) doped with poly(styrenesulfonic acid) (PEDOT:PSS), phthalocyanine, and inorganic CdS or CdSe single crystals on the other hand, has been studied depending on the crystal facet used. The effect of the surface‐terminated layer of the crystal on the PV performance of hybrid heterojunctions has been observed. It was found that the different crystal facets could render both quantitative and qualitative effect on PV properties of the hybrid heterojunctions.
