Spray deposition of polymer thin films investigated by in situ muGISAXS — •Adeline Buffet, Jan Perlich, Matthias Schwartzkopf, Gerd Herzog, Mottakin M. Abul Kashem, and Stephan V. Roth — DESY, Hamburg, Germany

Over the past few years organic-based hybrid devices have attracted increasing interest in both academy and industry because of their potential for low-cost production and flexible device applications [1]. Recently, the novel technique of airbrush deposition was used in the fabrication of organic-based multilayer devices such solar cells [2]. This technique allows for performing rapid deposition of organic-based thin film showing high homogeneity over large areas [3]. We used the versatile technique of microfocus beam Grazing Incidence Small Angle X-ray Scattering (muGISAXS, [4]) to investigate in situ the formation of a polymer thin film on a flat silicon wafer during spray deposition. Given the high photon flux available at the MiNaXS beamline of the PETRA III storage ring at DESY (Hamburg, Germany) in situ investigation of the polymer thin film build-up and of the nanostructure growth kinetics could be achieved with an exceptional time resolution of 50 ms.
