We evaluated the charge recombination rate in N719-sensitized nanocrystalline TiO2 films after photoinduced charge separation under substantially weak excitation conditions. We found that the recombination rates did not reach a constant value but instead decreased with decreasing light intensity. (C) 2009 Elsevier B. V. All rights reserved.
