Perovskite solar cells (PSCs) have aroused a wide range of interests in recent years due to their high power conversion efficiency. Traditional fabrication methods of perovskite layer such as one step spin coating, two step deposition and vapor deposition have been comprehensively studied for laboratory preparation. In this progress report, a rapidly developing methylamine (MA) gas based method is reviewed, which enables the large scale fabrication of high quality perovskite layer and extends the possibility of PSCs application in industrial preparation. The MA gas based method is related to solid-gas reactions, and the mechanisms of those special transformation processes of different solid-gas systems are discussed. Finally, a perspective of this promising PSCs fabrication method is given. However, as this method was only developed for a few years, there remain some unexplored areas for further investigation. |
