“…Furthermore, Hafid et al extensively reviewed the use of fins to improve the performance of a PV/T collector [9]. Irsyad et al also reported increasing the rate of heat transfer as in the case of the staggered heat exchanger with the fins acting as extended surfaces and thermal energy storage [10][11].…”

PV/T-TEC collector is a device that can produce thermal energy and electrical energy at the same time. The electrical performance may be increased by absorbing residual heat from the PV surface. Due to the temperature difference available between the hot and cold sides of this collector, additional electrical energy can be also generated by using the TEC to increase the total efficiency. The purpose of this study is to evaluate the thermal effect of using both fins and TECs acting as a heatsink. Thus, the perforated zone with a dimension of 100 x 50 x 2 mm was manufactured by lancing and bending processes. Furthermore, 44 pieces of TECs were placed inside the perforated-finned zone and were attached underneath the PV surface to allow a convection heat transfer process. The model collector was then tested by using a solar simulator under 1100 W/m2 with different fluid mass flow rates ranging from 0 to 0.339 kg/s. To meet the test requirements, environmental fluid flow was also implemented and simulated by a fan with an air velocity of 1 m/s. The results showed that increasing the air mass flow rate as a working fluid by five times can reach the operating temperature of the model collector by about 64 °C (24% decrease) and 74 °C (26% decrease) for both with and without environmental fluid flow, respectively. Meanwhile, under the same test conditions, the maximum value for the temperature difference of TEC sides is found to be 5.6 °C for both with and without ambient fluid flow.

“…Concerning the working fluid of a PV/T collector, it can be air or water which acts as a heat transfer medium, where the water-based PV/T system has higher electrical efficiency than that of an air-based PV/T system [10]. Based on the structure of a PV/T collector, the heat transfer area can be extended by using fins that serve as a heat sink for increasing the heat transfer rate [11]. To implement fins in heat transfer system, the cooling technique using rectangular microchannel heat sinks was also developed by Wan [12].…”

A photovoltaic (PV) collector converts sunlight directly into electrical energy about 20% while the rest is wasted as heat energy. This heat energy increases the operating temperature of the PV collector which has negative impacts on the semiconductor material and electricity production. Concerning the issue, the PV collector is then integrated by both the finned absorber and Thermoelectric Cooler (TEC) modules which is known as a PV/T-TEC collector. This study aims to determine the performance of the PV/T-TEC collector based on the tropical climate condition in Bandarlampung, Indonesia (latitude 5°27΄S and longitude 105°16΄E). Furthermore, the finned absorber and TEC modules are attached underneath the PV collector surface to act as a heat sink. Air as a working fluid was specifically passed through the PV/T-TEC collector to absorb the unused waste heat. Thus, the irradiation level and air mass flow rate are varied in the range of 700-1000 W/m2 and 0.0075-0.075 kg/s, respectively. Based on data obtained from the experimental tests, the highest values of the thermal and electrical efficiency are found to be 26.3 % and 9.8 %, respectively. The temperature difference between the two sides of the TEC is found to be less than 2.2 oC and there is a 0.3% increase in the total electric power generated from the TEC modules which cover 12% of the PV collector surface.
