Perovskite solar cells(PSCs) have been experienced a rapid development in last decade. One problem of this new type solar cells facing is that lacking of researches about fabricating PSCs via industrial technologies e.g. vacuum or printing based. Even the research purpose PSCs have reached 25.5% on the early of this year, the modules efficiency record is 17.9% only, according to the NREL efficiency chart. In this research, we are going to introduce some of our most recent results about fabricating PSCs via both vacuum and printing based technologies. The best PSCs adopting FAxCs1-xPbIyBr3-y absorber using both vacuum and printing technologies are 19.53% and 19.67%, respectively. We also developed some new technologies of improving perovskite films qualities based on these two technologies. Most recently, we successfully manufactured several m2 perovskite solar modules with a unit size of 20cmⅹ20cm. These perovskite solar modules are under field tests for evaluating their life time under real working conditions in Zhongshan ,Guangdong Province, China(Fig.1 ).
