Solar cells have experienced a rapid performance enhancement and price reduction in recent years, thanks to the technology innovation and governments' incentives. However, the growth of solar cell installation annually is still slow and it only accounts for 1∼2% of electricity generation globally. The slow processing and high capital cost limit the rapid expansion of solar cell market based on current technologies.Solution processable perovskite solar cells developed in the most recent decade hold the premise of low cost and rapid fabrication. Its efficiency increases dramatically from 3% in 2009 to 23.7% in 2018, being the record for all kinds of thin film solar cells. However, the high performance is obtained from tiny sized devices (< 10 mm2) by non-scalable spin-coating methods. The development of larger area perovskite solar modules by scalable fabrication methods lag far behind with efficiencies around 10%. The perovskite solution flow/drying dynamics, and perovskite crystallization in a scalable solution coating process are very different from spin-coating so that it becomes increasingly important of developing scalable, large area perovskite film coating methods. If high quality perovskite films can be obtained by scalable coting method with small area efficiency over 20%, the efficiency of perovskite solar modules (typically > 10 cm2) could go beyond 17.0% with efficiency loss from increased series resistance of larger sized transparent conductive electrode, being at the same level as commercialized silicon solar modules.In this dissertation, studies are focused on blade coating of perovskite films. Blade coating is one kind scalable coating method. It is compatible with other scalable coating process such as slot die coating, gravure coating, but it also has the advantages of simple set-up and freely tunable coating parameters (speed, temperature, thickness, etc.). Therefore, it is very suitable for preliminary study of perovskite scalable coating.
