What is photothermal phase change energy storage?

To meet the demands of the global energy transition, photothermal phase change energy storage materials have emerged as an innovative solution. These materials, utilizing various photothermal conversion carriers, can passively store energy and respond to changes in light exposure, thereby enhancing the efficiency of energy systems.

How a photothermal material converts light into heat?

2.4.3. Heat Transfer After the incident light is absorbed by a photothermal material, the photon energy is converted into thermal energy through a light-to-heat conversion process. The generated heat will be further transferred to other lower-temperature materials or released to the surrounding environment.

What is photothermal conversion?

(4) Moreover, energy transfer from light to heat occurs widely in physical, chemical, and biological reactions. It is one of the most fundamental processes in nature. This light-to-heat conversion process, where materials can act as light absorbers and efficiently transfer light energy into heat, is called photothermal conversion.

What are the advantages of photothermal nanomaterials?

One major advantage of photothermal nanomaterials is their broad light absorption range and excellent photothermal conversion ability, thus allowing for the efficient utilization of solar energy as a sustainable solution for energy scarcity.

What are the applications of photothermal materials?

The investigation of photothermal materials with broadband absorption is beneficial for the utilization of renewable solar energy, while the engineering of materials with efficient heat generation abilities can be widely useful in various fields, including water evaporation, (6,7) photothermal catalysis, (8,9) and biomedicine.

Why is heat transfer important in a photothermal conversion system?

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.
