Abstract As carbon neutrality becomes increasingly necessary, the utilization of renewable energy has become essential. Among these, solar energy is gaining popularity due to its ease of installation, maintenance, operation, and its status as an unlimited energy source. This study examines the efficiency of solar energy utilization by improving power generation efficiency and obtaining additional heat collection through the application of an air-based PVT system. The results show that the airflow behind the air-based PVT system lowers the panel temperature, leading to an average increase of 5.83% in power generation efficiency. Additionally, the temperature rise of the passing air resulted in heat collection rates of 38.04% in summer and 17.42% in winter. However, the heat energy collected in summer has relatively low usability. In this study, we proposed to utilize the collected energy acquired in summer as dehumidifying material for desiccant cooling, as it is relatively underutilized. In addition, mist cooling was performed as a method to reduce the enthalpy of the outside air during desiccant cooling, and the results showed that the enthalpy of the outside air was reduced by up to 23.2%, confirming the applicability of the proposed system.
