Abstract
The building sector is a significant contributor to global energy consumption and carbon emissions, necessitating the integration of renewable energy technologies. Photovoltaic–thermal (PVT) systems, which simultaneously generate electrical and thermal energy, can improve overall energy utilization efficiency in buildings. In particular, air-type PVT collectors are considered suitable for building applications because of their simple design and low leakage and freezing risks. However, their thermal performance is relatively limited owing to the low heat transfer coefficient of air. This study experimentally fabricated an air-type PVT collector with a perforated baffle plate designed to enhance internal airflow and heat transfer. Its thermal and electrical performances under outdoor conditions were analyzed. and compared with those of a conventional collector without a baffle plate.The results showed that the baffle plate improved the outlet air temperature increase, enhanced heat transfer within the collector, and increased the thermal and electrical efficiency coefficients from 0.2715 to 0.3175 and 0.138 to 0.154, respectively. Thus, by promoting airflow mixing and turbulence inside the collector, the perforated baffle plate effectively enhanced both its thermal and electrical performances. The proposed system shows potential for application in building-integrated renewable energy systems such as BIPV systems.
