Anotace

Atmospheric pressure plasma has become a standard tool for treatment of various surfaces. Due to the complex nature of the interactions between plasma and surface the applications of plasma treatment are very diverse, ranging from pretreatment of polymeric foils for better wettability and adhesion of inks, through etching of surfaces and disinfection of surfaces to improved germination of plant seeds [1]. Recently a new field of applications for atmospheric pressure plasma has emerged in post-deposition processing of printed functional coatings for flexible and printed electronics [2, 3]. The effects of plasma on coatings can include oxidation, or reduction of surfaces, passivation of defects on the interfaces, formation of multiple material composites, sintering of nanoparticles. Due to the possibility of igniting plasma in diffuse coplanar surface barrier discharge (DCSBD) in various gases including air, nitrogen, oxygen, hydrogen and argon, the process of plasma treatment of functional coating can be tuned to achieve the desired result. In this contribution we present a recent progress in atmospheric pressure, low temperature plasma treatment of functional coatings for a)oxidation of printed MXene coatings in oxygen plasma and formation of TiO2/MXene composite with possible applications as electron transport layer in perovskite solar cells or in photocatalysis, b)passivation of interfacial defects of mesoporous TiO2 electron transport layer in perovskite solar cells by hydrogen plasma for improved band alignment and charge transfer across the interface.
