Current spray-coating approaches to manufacture perovskite solar cells
Abstract
The research interest in perovskite solar cells (PSCs) is increasing because of the rapid developments in the recent times. PSCs exhibit exceptional photovoltaic performance, which is presently more than 25% for single-junction solar cells; thus, they have a high potential of achieving industrial commercialization and production. Nevertheless, the greatest issue faced by commercial applications is the device area of a PSC. Several fabrication techniques have been presented to create large-area PSCs such as slot-die coating, spray coating, blade coating and vacuum deposition. This paper reviews the spray coating method for the development of PSC. Developments in spray-cast PSCs that have occurred in the last few years are summarized in the study, with the focus on the deposition method, performance, morphology, stability, and large-area fabrication. It concludes that spray coating is the most suitable method for achieving the scalable manufacturing of large-area PSCs with moderate to high efficiencies.
