Performance Appraisal of Photovoltaic Module Combined with Various Optical Filters: Experimental Investigation
INTERNATIONAL JOURNAL OF RENEWABLE ENERGY RESEARCH(2023)
摘要
recent intensified structure of photovoltaic systems globally is a motivation to give a considerable attention for further efficiency improvement. The significant increase in surface temperature resulting from solar radiation is a major factor to the reduction in PV module power output. Currently, just ten to fifty five percent of the solar incident spectrum that hits a PV panel's surface today is converted to electrical power; the remainder is lost as heat. The thermal energy cumulation on the photovoltaic modules considerably reduces the electricity conversion efficiency. In the current study, five optical filters utilizing various working fluids are paired with a photovoltaic module and experimentally compared to the stand-alone photovoltaic module aiming to enhance its output and efficiency. In the current evaluation, the Monte Carlo technique is used to examine and compare the performance of the suggested optical filters. Glycerin, ethyl alcohol, oil, air, and water are the working fluids for the suggested configurations. The Monte-Carlo method indicates that the optical filter employing water has the maximum efficiency among the proposed working fluids. The consequences reveal that the electrical efficiency of the setup using water as a working fluid is the greatest, followed by structures using glycerin, oil, ethyl alcohol, air, and standalone PV modules, which have values of 7.74, 7.59, 7.51, 7.38, 7.19 and 5.17%, respectively.
