Temperature effects of CH3NH3PbI3 perovskite solar cells
having simple planar architecture were investigated on the
crystal structure and photovoltaic performance. The obvious
changes in the CH3NH3PbI3 crystal structure were found by
varying the temperature as a consequence to the augmentation in
lattice parameters and expansion of the unit cell. The expansion
of the crystal gave a serious influence on the performance of
the solar cells, where the differences in the coefficients of the
therma...
