Hybrid solar cells with ZnO nanorods and dry processed small molecule absorber

We demonstrate hybrid solar cells with ZnO nanorods ZnO NRs prepared by a low temperature electrochemical method and small molecule organic absorber processed by dry organic vapor phase deposition. A homogeneous coverage of ZnO NRs by the blend absorber consisting of zinc phthalocyanine ZnPc as donor and of fullerene C60 as acceptor is best realized when a thin C60 layer is first inserted at the ZnO NR ZnPc C60 interface. ZnO NR C60 ZnPc C60 MoO3 Ag solar cell devices with efficiencies of 2.8 under an illumination of 100 mW cm2 at 25 C are demonstrate
