The Prospects of Development of Photoelectric Convertors by Using Solar Energy in Georgia — •Ia Trapaidze, Rafiel Chikovani, Tengiz Mkheidze, and Gela Goderdzishvili — Georgian Technical University, Dep. of Physics,Tbilisi, Georgia

Georgia together with use of traditional energy resources attaches a very large importance of using renewable energy sources. The location of Georgia, the annual duration of solar radiation in the majority of areas ranges from 250 to 280 days, approximately 1900-2200 hours in a year. The prospects of development of solar photoenergetic devices in Georgia are analyzed. It is noted that the photoelectric method of conversion of the solar energy based on semiconductor materials is especially promising. It would be expedient to realize the production and application of solar photoelectric convertors in Georgia by stages in the scope of a complex research, technical and industrial program for 10-12 years. We have ve studied photoelectric converters on the base silicon, also GaAlAs. After research we observed that convertor obtained on the base of semiconductive compound of GaAlAs is more effective (2-2.5 times), than converter with silicon.
