عملکرد ساختمان های یکپارچه با جمع آوری فتوولتائیک ترمال و مواد تغییر فاز

To address the overheating of solar cell at midday in extreme hot summer regions as well as generate electricity with high and continuous photovoltaic efficiency, water-based photovoltaic/thermal-phase change material (PV/T-PCM) system has been proposed. A detailed simulation model for the system is presented. The effect of inlet water temperature as well as mass flow rate of the cooling water on performance parameters such as temperature of solar cell, photovoltaic efficiency is analysed. Results show that in comparison with the traditional photovoltaic panel, remarkable increase in photovoltaic efficiency has been actualized. Meanwhile, both increase in mass flow rate and decrease in inlet water temperature exert positive effect on performance parameters of PV/T-PCM system.
