Thermal Management Effective thermal management is essential in enhancing the efficiency of photothermal conversion systems, which convert solar energy into thermal energy. Here, we discuss strategies to improve thermal management by focusing on insulation, heat transfer mechanisms, and materials selection.
To optimize solar energy utilization, photothermal materials are engineered to maximize incident solar radiation absorption, while minimizing losses due to transmission and reflection. Furthermore, these materials are designed to convert absorbed photon energy into thermal energy efficiently.
The integration of PCMs with photothermal materials offers a promising strategy for the management and storage of thermal energy. By absorbing or releasing heat during phase transitions, PCMs facilitate enhanced temperature regulation and energy storage, which are critical in advanced thermal management systems.
Therefore, heat transfer is the third important process in a photothermal conversion system. The transfer of thermal energy from one material to another is driven by the thermal gradients between the materials, which can be realized in three main means, which are conduction, convection, and radiation.
