Query: Influence of the organic cation disorder on photoconductivity in
  ethylenediammonium lead iodide, NH3CH2CH2NH3PbI4   We report the synthesis and crystal structure of an organic inorganic
compound, ethylenediammonium lead iodide, NH3CH2CH2NH3PbI4. Synchrotron based
single crystal X-ray diffraction experiments revealed that the pristine and
thermally treated crystals differ in the organic cation behaviour, which is
characterized by a partial disorder in the thermally treated crystal. Based on
current voltage measurements, increased disorder of the organic cation is
associated with enhanced photoconductivity. This compound could be a potential
candidate for interface engineering in lead halide perovskite-based
optoelectronic devices.
