According to the sustainable development strategy, air-based photovoltaic-thermal (PVT) modules integrated with smart buildings are an effective and environmentally safe option for producing electricity and heating purposes to overcome the problem of scarcity and environmental pollution resulting from fossil fuels. Despite the importance of PVT modules, this technology has not achieved the required diffusion rates compared to other solar energy technologies due to its low overall efficiency. Therefore, the present study aims to develop the design of a heat transfer system integrated with PVT modules. To achieve this goal, the design of a heat transfer system was developed by adding 45° inclined fins integrated with the cooling channel to generate swirling movement near the back surface of PVT modules and increase the heat transfer area. To illustrate the best location for installing 45° inclined fins that achieve the highest performance improvement of PVT modules, we suggested two positions for installing 45° inclined fins and compared them with the dual-objective classical PVT modules (DO-CPVT) without fins. The first case is dual-objective PVT modules with top-inclined fins (DO-PVT&TIF). The second case is the dual-objective PVT modules with bottom-inclined fins (DO-PVT&BIF). The results presented that, dual-objective PVT modules with top-inclined fins (DO-PVT&TIF) represent a good design that achieves the highest performance. The improvement in thermal efficiency, electricity generation, overall energy efficiency, total exergy efficiency, and sustainability index for using DO-PVT&TIF modules reached 231 %, 11.5 %, 133.8 %, 19.3 %, and 4.3 %, respectively compared to classical DO-CPVT.
