Hybrid organic/inorganic perovskite materials have become promising candidates for photovoltaic applications. Typically, lab-scale perovskite devices are fabricated by spin coating under inert atmosphere conditions (inert gases and low relative humidity) which is incompatible with scaling-up processing. In this paper, we report the fabrication of perovskite solar cells in ambient conditions (average 65% relative humidity) and low temperature, by using a slot-die technique in a Mini Roll coater. A detailed optimization of the deposition parameters for the constituent layers in a flexible and planar perovskite solar cell is discussed. In particular, the resulting layers morphology strongly depended upon the processing temperature. The optimized device architecture reached a power conversion efficiency up to 2.9% with good reproducibility and reporting forward and reverse performance. The obtained results suggest that the slot-die processing of flexible hybrid perovskite solar cells at ambient conditions can be achieved with significantly reduced production costs and reliable and scalable technology.
