Abstract
The photoconductivity (PC) spectra of the compounds CH3NH3PbI3 , [CH3NH3][CH3C6H4CH2NH3]2Pb2I7 , [CH3C6H4CH2NH3]2PbI4 , [H2NC(I)=NH2]3PbI5 as well as the spectra of similar compounds bases on C10H21SC(NH2)2 , H3N(CH2)6NH3 , C14H9CH2SC(NH2)2 , SnI4 , PbClxI4-x and PbBrxI4-x are described. The position, intensity and shape of the PC bands depend on the dimensionality (or size) of the inorganic network as well as on the nature of metal halide and the organic groups. Excitonic features are discussed.
