AB  - Rising demands for renewable energy sources have led to the development of dye sensitized solar cells. It is a challenge to find a good and low cost sensitizer, which has a low environmental impact. In this work, we conducted spectroscopic and electrochemical experiments, as well as quantum-chemical calculations of the natural pigment hypericin, in order to provide insight into its sensitizing efficiency. To this end, three identical cells were made and characterized. Although this pigment exhibited good adsorption onto a semiconductor surface, a high molar absorption coefficient (43700 L mol(-1) cm(-1)) and favorable alignment of energy levels and provided a long lifetime of electrons (17.8 ms) in the TiO2 photoanode, it was found that the efficiency of hypericin-sensitized solar cells was very low, only 0.0245%. We suggest that this inefficiency originated from a low injection of electrons into the conduction band of TiO2. This conclusion is supported by the density functional theory calculations which revealed a low electron density in the anchoring groups of electronically excited hypericin. The results of this work could be valuable not only in the photovoltaic aspect, but also for application of hypericin in medicine in photodynamic therapy.

AB  - In this paper, electrical properties of inkjet printed graphene patterns on a PET-based (Novele (TM) IJ-220) substrate are presented. Water-soluble graphene conductive ink (Phene plus I3015) was used. Tested samples were printed with up to 12 layers. Desktop inkjet printer with 2000 dpi resolution was used for printing. After that, structures were sintered at 100 degrees C for 30 minutes. Printed patterns surface topography and profiles were observed using atomic force microscope (AFM) NTEGRA prima (NT-MDT). According to the results of AFM characterization, the thickness of 12 printed layers is similar to 750 nm. Measurements of electrical properties were performed with Hall effect measurement system at 0.37 T. Carrier mobility is 2330 cm(2)/Vs, while the conductivity is 389.11 1/Omega cm. All patterns are printed successfully with uniform structure and they are showing excellent compatibility with flexible PET-based substrate.

AB  - In this paper, we present the modeling, fabrication, measurement techniques, and characterization results of multilayer miniature coplanar waveguide (CPW) meander-type inductors for high-frequency applications. Detailed procedure of the fabrication process based on using ink-jet printing technology is given. Silver nanoparticle ink that contains 20 wt% of silver was printed on a flexible polyimide foil 50 mu m thick in one, two, and three layers. It is shown that multilayer CPW inductors have improved performance. Almost two times better Q-factor value was achieved. This is an encouraging result for multilayer printing in ink-jet technology.

AB  - This brief presents the transport parameters of silver layers on a polyimide substrate fabricated by an inkjet printing technology using nanoparticle inks with 20 wt% and 40 wt% silver. All the electrical characteristics of the samples were measured by Hall effect measurement system at 0.37 T. The electron mobility in inkjet printed silver layer was 7.07 and 4.58 cm(2)/V s for 20 wt% silver, 29.6 and 21.3 cm(2)/V s for 40 wt% silver at 77 and 300 K, respectively. The resistivity in inkjet printed silver layer with 20 wt% is 20.6 x 10(-6) and 27.1 x 10(-6) Omega cm, and 4.81 x 10(-6) and 8.27 x 10(-6) Omega cm for 40 wt% silver at 77 and 300 K, respectively. The surface morphology and profiles of the samples were obtained with an atomic force and scanning electron microscope.
