Glycoprotein turnover in hepatic microsomal membranes in rats during qualitatively different protein feedings

Parameters of glycoprotein carbohydrate turnover in hepatic microsomal membranes are significantly changed in test animals given qualitatively different protein feeding: sialic acid half life in the test rats decreased three times after 14 days. After 28 days the content of sialic acids returned to the control levels. The authors have made a conclusion that the time of sialic acid turnover may serve as a criterion in the evaluation of animal adaptation to varying rations.     

Two-Terminal Tandem Solar Cells DSC/<Emphasis Type="Italic">c</Emphasis>-Si: Optimization of TiO<Subscript>2</Subscript>-based Photoelectrode Parameters

New types of two-terminal tandem solar cells DSC/c-Si in which mesoscopic dye-sensitized solar cell (DSC) was connected in parallel with a crystalline silicon (c-Si) solar cell, were developed and investigated. We have measured the optical and photovoltaic parameters for both the individual and the fabricated tandem DSC/c-Si solar cells. It was shown that the highest efficiency of 14.7% for the tandem DSC/c-Si solar cell under standard AM1.5G (100 mW/cm²) illumination conditions was achieved for DSC based on 3.5 μm thick titanium dioxide photoelectrode.     

Power Conversion Efficiencies of Perovskite and Dye-Sensitized Solar Cells under Various Solar Radiation Intensities

Semiconductors - We present the results of a comparative study on behaviour of the photovoltaic parameters in perovskite (PSC), dye-sensitized (DSC) and crystalline silicon (c-Si) solar cells under...     

Novel Types of Dye-Sensitized and Perovskite-Based Tandem Solar Cells with a Common Counter Electrode

Novel types of tandem solar cells (TSC) based on dye-sensitized (DSC) and perovskite (PSC) solar cells including DSC/DSC and DSC/PSC configurations with a common counter electrode were fabricated and investigated. The measurements of PV parameters for tandem solar cells under AM1.5 light intensity conditions have shown that the highest power conversion efficiency (PCE) of 14.5% was obtained for the DSC/DSC tandem configuration. At the same time, investigations of DSC/PSC tandem solar cells demonstrated the prospective benefits of this tandem system for obtaining high PCE values.
