It is possible to use it in the production of perovskite absorbers as well as charge transport layers (CTL). Because there is a vacuum inside the chamber, vapor particles are able to migrate more quickly and easily to the substrate, where they can then condense back into a solid.
In order to bring perovskite solar cells into the commercial market, it is necessary to improve and optimise the current fabrication methods and conduct further research. Combining or optimizing technologies is typically needed to balance performance, cost, and manufacturing efficiency. 1. Introduction
A solar cell device was selected for this first demonstration of doping in a perovskite device due to the large body of knowledge in optimizing their architecture. With the latest record efficiency of the perovskite solar cells (PSC) being 26.1%, they are approaching the Shockley-Queisser limit.
We cover all the methods for making perovskite devices, including the two steps and one step deposition processes that make high performance PSCs, in this review. A number of techniques were studied, including spin coating, SC, drop casting, doctor blading, CVD, and vacuum thermal evaporation.
However, the first use of spray-coated perovskites in solar cells was reported by Barrows et al. in 2014 . Tiny droplets of solution are adhered to the surface using the current SC process, which employs an extremely sharp and fine nozzle (Fig. 11).
The perovskite precursor solution was prepared by dissolving 0.72 m PbAc 2 ·3H 2 O and 2.2 m MAI in DMF and stirring at room temperature for 30 min. The solution was filtered through a 0.45 µm PTFE filter and spin coated at a spin rate of 6000 rpm for 2 min.
