The perovskite solution was spin coated on the sno 2 substrate in a two step at 1,000 and 4,000 rpm for 10 and 30 s in the nitrogen environment, respectively.During the second step, 400 l diethyl ether was drop casted quickly 10 s before the end of the second step.The perovskite films were then heated at 150c for 10 min.
