The recent steady improvements in the performance of the nascent hybrid perovskite photovoltaic (PV) devices have led to power conversion efficiencies that rival the best-performing established PV technologies. However, to scale these laboratory demonstrations to PV module-scale production will require development of scalable deposition methods for perovskite thin films. Every record result for perovskite PVs so far was achieved via spin coating, a technique that is popular in research laboratories for thin-film coating over relatively small device areas, but not considered to be a method that could be used to scale up the manufacturing of perovskite PVs. Significantly larger thin-film areas are needed for future commercial PV products. Hence, some researchers have focused their efforts on perovskite deposition techniques that can be considered as scalable for mass production and have achieved notable results even on large areas. Here, we present an overview of the solution-based and vapor-based deposition processes; we explain their influence on the molecular crystal growth behavior of perovskite thin films and discuss the morphology as well as other material quality characteristics. By presenting a comprehensive comparison of the deposition techniques and the corresponding performance parameters for different device sizes, we intent to guide the growing research community through the methods that might enable mass production of perovskite solar products.

By controlling the process parameters, such as substrate temperature, spray flow rate, number of spray passes, and solution concentration, 11,19,20,22,23,32,35 or applying dynamic forces on the substrate, such as ultrasonic vibration 2,5 or mechanical force (pressing), 22 the spraying process may become controllable to some extent. In some recent works, progress has been made toward fabrication of high efficiency spray-on SCs in both organic and perovskite devices.…”

Optimization of spray coating for the fabrication of sequentially deposited planar perovskite solar cells

Abstract. We use facile coating techniques including spray coating and drop casting to fabricate methylammonium lead iodide perovskite solar cells through a two-step sequential deposition approach. In the first step, for the deposition of the lead iodide, spray coating substitutes for the commonly used lab-scale spin coating, while the operating parameters of the former process are optimized to achieve a fully covered and uniform film of lead iodide. In the second step, to deposit methylammonium iodide atop the lead iodide layer to form methylammonium lead iodide perovskite, dip-coating process is replaced by the touch-free drop casting and scalable pulsed-spray coating. It is found that the performance of the perovskite films and devices made by pulsed-spray coating and drop casting is similar to those prepared by dip coating, while the large-scale production capabilities of such methods beside the low material consumptions of drop casting prove their potential to replace dip coating in large-scale manufacturing of perovskite solar cells. The champion devices fabricated by spray-drop and spin-drop techniques demonstrated power conversion efficiencies of 6.92% and 9.48%, respectively. It is expected that device fabrication in a low-humidity environment using the optimized parameters and optimization of other layers will result in higher efficiencies. © The Authors.
