Silicon photovoltaic converters with nanocomposite thick coatings

A perspective design for the photoelectric converter with the thick-film antireflection polymer composite material coatings based on silver in the matrix of polymethyl methacrylate is shown. The way of increasing the efficiency of photoconversion, the essence of which is the use of additional phototransducer usable space and scattering back to the border for the incident photons. The role of size effect in increasing the efficiency of solar cell is shown by 8...10 % when using composite coatings with silver nanoparticles size of 25...30 nm and 30...35 % using coatings with silver microparticles 150...200 microns.

Keywords: photoelectric conversion cell, composite materials, nanocomposite antireflection coating.

Investigation of the device noises in the fiber-optic system for monitoring patohenic microorganisms

In this article we have considered the problem of minimizing the error associated with the noise in the optical channel. This is required to automate the method of the optical control of pathogenic microorganisms in water flow. We investigated errors associated with the loss of power of the optical signal and with the diffraction in the waveguide. We studied form of the parasitic optical modes and their wavelengths. We have identified informative parameters that allow distinguishing between the useful signal and error.

Keywords: optical scattering, liquid medium, rapid analysis, pathogenic microorganisms in flow of water.

Minimizing Temperature Dependency of Electrical Resistance Standards

It is proposed to manufacture electrical resistance standards in the range of 1 Ohm...10 kOhm using resistive temperature transducers. The resulted first-order temperature coefficient of resistance of each resistance standard is reduced to a level of 0,01 ppm/K. Minimization TCR allows improving of accuracy of the calibration of electrical resistance standards without any specific temperature control.

Keywords: electrical resistance standards, temperature coefficient of resistance (TCR), first-order temperature coefficient, second-order temperature coefficient, minimization TCR, resistive temperature transducers.
