چکیده
The present paper presented an experimental work to enhance the photovoltaic cells performance. A heated aluminum plate is used simulate PV solar cell. effect of different phase change material (PCM) type, heat sink configurations, PCM mixed with Al2O3 nanoparticles at volumetric concentrations from 0.11 0.77% are experimentally investigated. PCMs RT28HC, RT35HC and RT44HC which have melting point near cell reference temperature. Three sinks hollow cylindrical fins, 11, 18 22 act as thermal conductivity enhancer (TCE) improve transfer rate achieve uniform distribution within PCM. experiments carried out for free surface-simulated cell, simulated only, pure finally nanoparticles. results show good enhancement in reduction front surface temperature highest 57.7% that occurs flux 820 W/m2 copper fins immersed mixture RT44HC-Al2O3 concentration by volume T? = 21 ± 1 °C.
