Abstract

This work demonstrates the use of diffuse coplanar surface barrier discharge (DCSBD) plasma as a low-temperature, solvent-free method for scalable fabrication of perovskite solar cells (PSCs). Operating below 70 °C and at atmospheric pressure, DCSBD plasma enables rapid sintering of TiO₂ and SnO₂ electron transport layers (ETLs), activation of indium tin oxide (ITO) electrodes, and surface passivation of MAPbI₃ perovskites. These treatments improve crystallinity, wettability, and charge transport, achieving efficiencies comparable to conventional methods while reducing energy demand. The approach offers a sustainable route for roll-to-roll production of flexible PSCs.

Keywords: Perovskite solar cells (PSCs); diffuse coplanar surface barrier discharge (DCSBD); atmospheric plasma; low-temperature processing; TiO₂; SnO₂; ITO; MAPbI₃; roll-to-roll fabrication
