Recent rapid growth in perovskite solar cells (PSCs) has sparked research attention due to their photovoltaic efficacy, which exceeds 25 % for small area PSCs. The shape of the perovskite film directly governs its optical and electrical characteristics, such as light absorption, carrier diffusion length, and charge transport.
We systematically analyzed our solar cell stacks and found that the pristine MAPbI 3 films show well-suited morphology and optoelectronic properties for solar cell application. The film properties further improve by posttreatment via (hot-)pressing, leading to increased grain size, crystallinity, crystallographic orientation, compaction
Natural drying (without spin coating or assistance of antisolvent, gas, or vacuum) might be the least-cost drying method to make perovskite films for solar cells. However, perovskite films made without quenching generally show undesirable morphology and low

Introduction
Although previous studies have explored perovskite film formation using CVD, this study marked the pioneering application of this technique to solar cells. The authors compared solar cell efficiencies by varying the thickness of the precursor film, PbCl 2, and the annealing atmosphere.
The more uniform and better-interconnected films throughout the film's thickness for the DASSA films allow for the photo-generated carriers to propagate through the films with less defects which will lead to better performance in solar cells.
Spray coating Spray coating (SC) was used for the first time to create perovskite thin films, which were based on the building of a polymer solar cell . Thin films of organic PV and oxides have been created using this technique. However, the first use of spray-coated perovskites in solar cells was reported by Barrows et al. in 2014 .
Moreover, dry deposition techniques exhibit excellent compatibility with perovskite/silicon tandem solar cells [ 21, 22, 23 ]. When depositing conformal perovskite films on textured silicon surfaces, the dry processes ensure efficient light harvesting and improve device performance in tandem solar cell configurations.
