title: Thermally-activated recombination in one component of (CH3NH3)PbI3/TiO2 observed by photocurrent spectroscopy.
abstract: Photocurrent measurements on devices containing perovskite (CH3NH3)PbI3 show two distinct spectral responses when deposited in a mesoporous oxide matrix, compared with one response for planar perovskite alone. With a TiO2 matrix, the shorter wavelength response has an inverted temperature response with increasing performance on cooling.
