Increase of efficiency of photoelectric transformers of solar concentrated energy on the basis of III-V semiconductor compounds — •Ia Trapaidze1, Rafael Chikovani1, Gela Goderdzishvili1, Temur Khachidze1, and Lia Trapaidze21Dep. of Physics, Georgian Technical University, 77 Kostava, 0175 Tbilisi, Georgia — 2Dep. of Physics, Tbilisi State University, 3 Chavchavadze Ave., 0179 Tbilisi, Georgia

Georgia, as the Southern country is rich of solar energy. It is located in the Sun's belt. Using of solar energy for receiving the electrical and thermal energies is very important for Georgia. To increase the efficiency of using of solar element there are used the concentrators of optical radiation. They provide with concentration of incident beam energy on a wide area (on the surface of a concentrator) on relatively small area of a semiconductor crystal, which increases the power of electronic energy generated (labored out) by the photocell. And this means the increase of efficiency of using of the solar cells.

For the purpose to make more effective the removal of heat from the photocells, we consider it expedient to develop a new system for using to heat relieved from the photocell for heating the water.
