Abstract: This study summarizes the performance of a photovoltaic/thermal (PV/T) system integrated
with glass to tedlar and glass to glass photovoltaic (PV) cells protections. A dual‐fluid heat exchanger
is used to cool PV cells in which water and air are operated simultaneously. The proposed PV/T design
brings about a higher electric output, while producing sufficient thermal energy. Detailed numerical
study was performed by calculating real‐time heat transfer coefficients. Energy balance equations
across the dual‐fluid PV/T system were solved using ordinary differential equation (ODE) solver in
MATLAB software. The hourly and annually energy and exergy variations for both configurations
were evaluated for Cheonan city, Korea. A larger surface area in case of PV/T system with glass to
glass configuration cases the acquisition of extra solar heat and hence improvement in convection heat
transfer coefficient. Results depict that the annual electrical and total thermal efficiency of the PV/T
system with glass to glass and glass to tedlar configurations were found to be 13.6% and 57.9%, and
13.2% and 53.2%, respectively. It is also observed that with the application of dual‐fluid heat
exchanger the temperature gradient across the PV panel is surprisingly reduced.
