MAQOLA ANNOTATSIYASI

Cooling of the rear surface of photoelectric batteries (PEB) was investigated by attaching a newly designed heat collector made of parallel channel cellular polycarbonate to the rear surface in order to improve the electrical and thermal efficiency in this research work. The experiment was conducted on June 7, 2022 at the Heliopolygon of the Physical-Technical Institute of Tashkent city (latitude: +41,34 (41°20'23"N), longitude: +69,3 (69°17'36"E). 2 340 W monocrystalline silicon PEBs(photoelectric batteries) were used as experimental devices. The rear surface of the first is equipped with a cooling system. The second are unadjusted for comparison purposes. A heat collector is attached to cool the back surface of the PEBs(photoelectric batteries), called a photothermal battery (PTB). Water was used as the cooling liquid of the photothermal battery (PTB). The increase in electrical and thermal efficiency depending on the change in the flow rate of the coolant was analyzed. In addition, the dependence of the solar radiation on the frontal surface of the photothermal battery (PTB) on the inclination angles of the flux density enhancing reflectors and the support structure moving in relation to the sun on two axes was also investigated. Electrical and thermal efficiencies were observed for 0,067, 00,1 and 0,2 kg/s flow rates of 210C water in the consumer pipe to the heat collector.
