The external quantum yield of photoresponce of tandem solar cells

Published in category «Condensed matter physics»

Theoretical approaches which allow to calculate spectral dependences of external quantum yield of multijunction tandem solar cells have been considered; spectral characteristics of single-junction Ge, double-junction GalnP/GaAs and triple-junction GalnP/GaAs/Ge solar cells were calculated. The possibility of application of these approaches to investigation of minority carrier diffusion lengths in active regions of the solar cells through the comparison of experimental and calculated spectral characteristics was shown. Found out the values of minority carrier diffusion lengths for the layers of GalnP/GaAs/Ge solar cells, which provide almost full collection.

Composite C60CdS thin films for photoelectronics

Published in category «Condensed matter physics»

The technique of production of a new composite material including organic and inorganic semiconductors has been worked out to achieve a bulk geterojunction based on donor-acceptor complex. Optical spectra of C60CdS composite thin films were obtained and analyzed and a charge-transfer-solid-state complex formation was determined.

A way of calculation of molecular effect under ion irradiation based on threshold density of collision cascade

Published in category «Condensed matter physics»

A way of calculation of molecular effect in stable damage buildup in crystalline lattice under accelerated ion irradiation that takes into account nonlinear energy spikes is described, it is shown that the length of cubic cell edge influences only on the level of critical vacancy concentration and has no influence on coincidence of experimental and calculated curves.

Hypothetical model of the excess metabolism of yeast utilizing liquid n-alkanes

Published in category «Biophysics and medical physics»

The authors assume that cells adsorbed on drops can experience an excessive metabolism of a hydrophobic substratum and the process emits intermediate products of oxidation to increase mitochondrial and cytoplasmic membranes permeability, separate oxidizing phosphorylation process, raise consumption for maintenance of vital functions and increase energy dissipation. This mechanism is similar to maintenance of temperature in cells of warm-blooded animals brown fat running into hibernation.

Magnetic rotation of the light polarization plane disseminated by erythrocytes suspension

Published in category «Biophysics and medical physics»

The turn of a polarization plane of the light disseminated at app. 180° by the erythrocytes suspension in physiological solution, diluted with a buffer solution is found in external magnetic field. Verde constant and coercive force are defined. Results are interpreted on the basis of a model according to which magnetic properties of blood are caused by the magnetic moment of the heme, being a part of a myoglobine molecule and containing a bivalent iron ion in the porphyrine ring.

The correlation function analysis of noise signals using an adaptive processor based on the echo phenomenon

Published in category «Simulation of physical processes»

Some experimental results on echo-signals-making from noise pulses in thin cobalt films have been presented. A theoretical explanation for these results is offered; that makes it possible to predict the conditions under which echo signals are bound to be a correlation function of noise pulses of excitation.
