| description | The primary limitation of photovoltaic thermal (PVT) technologies is the adverse effect of solar irradiance-induced heat absorption. In order to enhance the efficiency of the system, it is essential to incorporate a cooling mechanism. The utilization of a reversed circular flow jet impingement (RCFJI) was implemented as a cooling mechanism for a bifacial PVT solar collector. This study aims to analyze the exergy efficiency of a RCFJI bifacial PVT solar collector. An indoor experiment was conducted using a solar simulator with a solar irradiance of 500–900W/m2 and a mass flow rate of 0.01–0.14 kg/s. The findings revealed that the highest photovoltaic exergy attained was 47.2W under solar irradiance of 900W/m2 and a mass flow rate of 0.14 kg/s. Meanwhile, the highest thermal exergy attained was 9.67W under 900W/m2 solar irradiance and 0.14 kg/s mass flow rate. Overall, the exergy efficiency attained a maximum value of 12.64% under 900W/m2, while the lowest exergy efficiency observed was 12.25% under 500W/m2. In addition, the optimal operational mass flow determined was 0.06 kg/s. The findings indicate that the optimal performance of the RCFJI bifacial PVT solar collector is achieved through higher exergy efficiency, which signifies a reduced requirement for input energy. Consequently, more energy can be harnessed. |
