Sputtered PbI₂ with Post‐Processing for Perovskite Solar Cells

Abstract

Perovskite Solar Cells In article number http://doi.wiley.com/10.1002/solr.202300214, Kang, Lee, and co‐workers presented a novel approach for fabricating perovskite films using a sputtering process. They applied post‐processes to enhance the film properties and the electrical characteristics of perovskite solar cells. These processes enable the deposition of uniform perovskite films on large‐area textured silicon substrates, opening new possibilities for efficient solar energy conversion.

Inorganic Framework Composition Engineering for Scalable Fabrication of Perovskite/Silicon Tandem Solar Cells

“…Ligand strategies have emerged as a prominent approach to alleviating the dense arrangement of PbI 2 in the first step. By forming ligands with PbI 2 and subsequently replacing them with organic salts, these strategies influence reaction pathways and rates, driving favorable perovskite formation. − While in the cases of hybrid two-step method prepared on textured silicon as substrates, the first step is more challenging to control the inorganic components or form ligands compared with the solution method. Yi et.al introduced a Cl-containing alloy-mediated approach in a sequential vacuum evaporation method, enhancing perovskite film quality by promoting organic ammonium halide diffusion and perovskite conversion reaction .…”
