Abstract
This study introduces a solvent-free close-spaced sublimation (CSS) method for both perovskite conversion and post-treatment. A PbI2 layer is deposited via thermal evaporation and subsequently converted into MAPbI3 using CSS of Methylammonium iodide powder. The resulting MAPbI3 layer is further passivated with MACl powder using the identical CSS method. Through this post-treatment, it is possible to improve the quality of the perovskite layer, leading to a decrease of defect density and enhancing photovoltaic performances. As a result, device efficiency improves from 14.6% to 16.4%, with notable increases in Jsc and Voc, along with a reduction in hysteresis. The potential of this solvent-free CSS method is demonstrated, making it a promising approach for large-scale manufacturing of perovskite and tandem solar cells.

期刊介绍:
Solar RRL, formerly known as Rapid Research Letters, has evolved to embrace a broader and more encompassing format. We publish Research Articles and Reviews covering all facets of solar energy conversion. This includes, but is not limited to, photovoltaics and solar cells (both established and emerging systems), as well as the development, characterization, and optimization of materials and devices. Additionally, we cover topics such as photovoltaic modules and systems, their installation and deployment, photocatalysis, solar fuels, photothermal and photoelectrochemical solar energy conversion, energy distribution, grid issues, and other relevant aspects. Join us in exploring the latest advancements in solar energy conversion research.
