Organic-inorganic perovskite compound CH3NH3PbI3 attracts much attention because of the high efficiency. For practical application, however, toxic lead and low stability of it must be improved. Using first-principles calculation, we have studied stability of the perovskite structures represented as ABI3 (A=CH3NH3, Cs, and CH(NH2)2 and B=Pb, Sn, In etc. ). Our results suggest that bonding state between A and I have an influence on structural stability in the solid solution.
