Experimental Investigations of the Effect of Temperature on Power in a Combined Photovoltaic Cell and Thermo-Electric

摘要

Abstract In this paper, a combination of thermoelectric (TEG) and low power mono-crystalline photovoltaic cell (PV) has been designed and fabricated. The experiment was to investigate and analyze the effect of temperature on PV cell and to investigate the output power generated by TEG under two (2) different levels of irradiance. The temperature and output power of their characteristics within the system set up are determined. Experimental investigation tests have been carried out under solar simulator using halogen light as a light source. Analysis on combined system Photovoltaic Cell/Thermoelectric Generator (PV/TEG) has been conducted based on the different temperature effects at irradiance of 1000 and 750 W/m2. At irradiance of 750 W/m2, the maximum temperature at the PV cell hot side was 61 °C, while the output power of TEG and PV cell were 0.0039 W and 2.49 W, respectively. Results have shown that the efficiency of PV cell was improved by 1.4% when PV/TEG system was applied; maximum efficiency of PV cell at irradiance of 750 W/m2 is 12.18% and when the temperature was 30 °C.
