Abstract

Anti-solvent-free one-step deposition of perovskite thin film shows promising potential for application in slot-die or roll-to-roll mass-fabrication processes of perovskite solar cells. The continuous coverage was confirmed by PV response of devices made using the one-step deposition process. In this work, we have developed a process to deposit MAPb_0.75Sn_0.25(I_0.5Br_0.5)₃ perovskite thin films without anti-solvent adding MAAc to the ink. By varying the Br content of the perovskite precursor, we were able to tune the bandgap. Fabricated solar cells with the structure ITO/CuI/ MAPb_0.75Sn_0.25(I_0.5Br0.5)₃ /C₆₀/BCP/Al with PCE of 4.59% show the path of the fabrication process of antisolvent-free tin-lead-based solar cells
