An Experimental Study on the Effect of Phase Change Materials on the Performance of a Photovoltaic/Thermal Solar Chimney in a Greenhouse

Summary

Tests a greenhouse solar chimney prototype with a central photovoltaic module and absorber that split the airflow into two symmetric channels. Running both channels together gives the fastest airflow. Adding phase change material behind the PV panel keeps ventilation going when sunlight is weak, cooling indoor air by about 5 °C and raising peak electrical efficiency by 4.6%.
