本文报道了化合物CH_3 NH_3 PbI_3、[CH_3 NH_3][CH_3C_6 H_4CH_2NH_3]_2 Pb_2 I_7、[CH_3C_6 H_4CH_2NH_3]_2 Pb_4、[H_2NC（I）= NH_2]_3 Pb_5的光电导谱，以及以C_（10）H_21）SC（NH_2）_2、H_3 N（CH_2）_6 NH_3、C_（14）H_9 CH_2SC（NH_2）_2、SnI_4、PbCl_xI_4-x和PbBr_xI_4-x为基础的类似化合物的光电导谱。PC谱带的位置、强度和形状取决于无机网络的维度（或尺寸）以及金属卤化物和有机基团的性质。激子功能进行了讨论。
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.
