eng	Photoacoustic Measurements for the Evaluation of Printed Layers	In order to obtain a good functionality of printed thin conductive layers and consequently devices reliability, the physical properties of the layers need to be observed. The parameter of the thickness of printed functional layer is applied as an example. This parameter can be determined either by mechanical (or optical) profilometers or by using e.g. spectroscopic methods, such as the UV-VIS or the photoacoustics. Since the promising results have been obtained after the first photoacoustic measurements carried out on the spiral coated functional layers, further measurements have been done to prove this method for the determination of layer thickness with the screen printed transparent conductive polymer layers on transparent and non-transparent substrate. The examined materials are represented by the commercially available conductive ink on the base of PEDOT:PSS, prepared on different substrates, such as the transparent PET foil and the non-transparent raw white polycarbonate foil.
