000188547 520__ $$aOrganic-inorganic hybrid systems based on lead halide compounds have recently encountered considerable success as light absorbers in solid-state solar cells. Herein we show how fundamental mechanistic processes in mesoporous oxide films impregnated with CH3NH3PbI3 can be investigated by time resolved techniques. In particular, charge separation reactions such as electron injection into the titanium dioxide film and hole injection into the hole transporting material spiro-OMeTAD as well as the corresponding charge recombination reactions were scrutinized. Femtosecond transient absorption spectroscopy and time-resolved terahertz spectroscopy were applied to CH3NH3PbI3 deposited either on TiO2 or Al2O3 mesoporous films and infiltrated with the hole transporting material spiro-OMeTAD.
