	Sputtered coatings of SiNx:H on H2 plasma etched mono-Si substrate Hégr, O. ; Boušek, J. ; Fořt, Tomáš ; Sobota, Jaroslav ; Vavruňková, V. ; Bařinka, R. ; Poruba, A. The paper deals with cleaning, activation and ability of hydrogenation of monocrystalline silicon surface with the help of plasma etching in H2. Using the input gases Ar/H2 it is possible to initiate silicon surface chemical reactions acting similar to a standard chemical etching. The process is combined with deposition of SiNx:H layers on plasma etched substrate. Detailed record
	Optical properties of thin films measured by PDS Remeš, Zdeněk Description of the photothermal deflection (PDS) spectrometer used in the Institute of Physics of the ASCR. Applicatons include the optical absorption in thin conductive oxides and thin films solar cells. Detailed record
	Characterization of structural and electronic properties of organic heterostructures by scanning probe techniques Čermák, Jan ; Rezek, Bohuslav ; Cimrová, Věra ; Hörhold, H. H. ; Ledinský, Martin ; Fejfar, Antonín Study of morphologic, electronic and optoelectronic properties of organic heterostructures by AFM, KFM, CS-AFM and micro-Raman mapping. Detailed record
	Charge transport at polypyrrole diamond interface Rezek, Bohuslav ; Čermák, Jan ; Kromka, Alexander ; Ledinský, Martin ; Kočka, Jan Changes of surface potential and photo-current under illumination indicate exciton splitting at the polypyrrole-diamond interface and transport of holes to diamond. Detailed record
	A curve template for I-V characteristics of the solar cells Fejfar, Antonín The contribution describes a computer program for manual fitting a theoretical dependence of the current flowing through a solar cell on the voltage in a way corresponding to flexible curve templates. The template provides handles "attached" to the curve for intuitive and independent manipulation of the parameters. This makes it possible to judge the sensitivity of the fit to the individual parameters. Detailed record
	Characterization of multicrystalline solar cells with LBIC method in different wavelength Fořt, Tomáš ; Jandová, K. ; Vaněk, J. ; Boušek, J. For the determination of defects in the solar cells was used a method LBIC (Light Beam Induced Current). We use LED light source with various wavelengths to reveal the different types of defects. Using multiple wavelengths enables detecting defects in different depths. Surface defects can be observed in shorter wavelengths (400nm and 470nm). The junction region is well observed at wavelengths close to 525nm. Defects in the base material are visible using the light at a wavelength of 630nm or 890nm. Detailed record
	Study of titanyl pthalocyanine and fluorene-thiophene copolymer thin films by the surface photovoltage method Toušková, J. ; Toušek, J. ; Cimrová, Věra ; Pavlačková, Petra ; Remeš, Zdeněk Thin films of titanyl phthalocyanine (TiOPc) and fluorene-thiophene copolymer (FIPT) were studied by the surface photovoltage method (SPV). Using modified SPV theory, exciton diffusion lengths and thicknesses of a space charge region (SCR) generated at the free surface were determined. Short drift lengths of the charge carriers in the SCR indicate high recombination. The recombination losses result in a lower photovoltage measured for illumination from the free surface side than that for illumination from the substrate side. Detailed record
