    Charge generation and transport in (CH sub(3)NH sub(3))PbI sub(3-x)Cl sub(x) sensitized mesostructured solar cells are investigated. A highly efficient charge generation is directly proven by time correlated single photon counting analysis. Photoinduced absorption and transient photovoltage investigations depict double charge recombination dynamics. To explain the high device performances according to those spectroscopic observations, we suggest the existence of two complementary paths for electron transport, involving either TiO sub(2) or perovskite matrixes.
