Inorganic-organic hybrid photovoltaics offer a cost-effective alternative to traditional inorganic solar cells. The electronic devices can be fabricated from solution using industrially viable printing and coating techniques. The ideal hybrid photovoltaic device possesses an ordered bulk heterojunction in which the polymer donor and the inorganic acceptor domains are vertically aligned to the electrodes to form periodic patterns. However, it is challenging to produce such an ordered structure in a manner compatible with solution-based fabrication. Here, we report novel hybrid inorganic-organic core-shell nanowires with precise control of interface via covalent bonding of side-functionalized conjugated polymers onto inorganic semiconductor nanowires. The resulting anisotropic nanohybrids serve as the photovoltaic elements and could be vertically aligned using traditional screen-printing. The structure-property correlations will be addressed.
