Dept. of ECE and CAMTEC, University of Victoria, Victoria, BC, Canada aut Field-enhanced charge flow in nanorod heterostructure solar cells [Elektronische Daten] [H. Kwok] Recent studies on organic heterostructure solar cells have indicated that interface morphology plays an important role in determining the quantum efficiency. Hybrid heterostructure mixing donor and acceptor semiconductors appear to offer the best opportunity in achieving superior performance and there are indications that a network of percolated heterojunctions can be quite effective in promoting light absorption and exciton quenching. Charge transport and collection efficiency, however, appear to be more complex in the bulk heterostructure and the nature of charge flow depends largely on the type of current paths in existence. We report in this work the possible existence of field-assisted charge flow in the nanorod heterostructure solar cells when carriers of different polarity move in close proximity. The field-effect associated with the charge density gradients can exert a force on the nearby carriers resulting in an increase in the short-circuit current. The model is used to explain data reported in the literature on solar cells composed of TiO2 nanorods embedded in a conjugated polymer.
