Aerosol Flow Homogenization in the Spray Polyphenylene Vinylene Thin Film Deposition

Abstract

Two different spray deposition (SD) techniques were compared on polyvinylene (MDMO-PPV) used as a model material. SD and homogenized (h-SD) techniques were compared. Films of about 1 micron thickness were prepared by SD and h-SD and normal techniques from toluene solution with a concentration of 0.5 g/l. It was found that the ITO|MDMO-PPV|Al structures with h-SD MDMO-PPV films behave as a photovoltaic cell. Optical micrograph images show structure with typical discs. Current - voltage characteristics measured on samples with h-SD films show that an exposure to a white light increases the current two orders of magnitude.Two different spray deposition (SD) techniques were compared on polyvinylene (MDMO-PPV) used as a model material.
