Research on perovskite solar cells has entered a new era. At the next stage, it is necessary to develop methods to fabricate large area cells and modules with improved stability. We have developed a chemical vapor deposition (CVD) method to deposit perovskite films [1-3]. We fabricated methylammonium (CH3NH3+, MA+) MAPbI3 solar cells with PCE up to 15.6% (active area = 0.09 cm2), formamidinium (NH2CH=NH2+, FA+) FAPbI3 cells with PCE up to 10.4% (active area = 2.0 cm2), FAPbI3 modules with PCE up to 9.5% (5-cell modules; total active area = 8.8 cm2) and 9.0% (6-cell modules; total active area = 12 cm2) [1]. Also, we demonstrate that better thermal stability cab be achieved with FAPbI3. References:[1] Leyden, M. R.; Jiang, Y.; Qi, Y. B.*; J. Mater. Chem. A 2016, 4, 13125.[2] Leyden, M. R.; Lee, M.
