Principle of photothermal lava energy storage technology

What is solar energy photothermal conversion & storage?

For solar energy photothermal conversion and storage systems, materials not only have efficient photothermal conversion capabilities, but also provide a place for storage and energy exchange for phase change media, while avoiding problems such as leakage and poor thermal conductivity during the phase change process.

How can photothermal conversion materials solve the solar energy imbalance?

Using photothermal conversion materials to capture solar energy, energy conversion, and then through phase change materials to store solar energy can effectively solve the imbalance between the use of solar energy in time and space supply and demand.

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.

Why do we need a photothermal storage media?

These factors hinder the continuous energy conversion of photothermal materials, necessitating collaboration with storage media. The mismatch between demands and supplies in time and space can be efficiently addressed by utilizing PCM to store solar energy after it has been captured and converted using photothermal conversion materials.

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 is a photothermal process?

A photothermal process is a direct conversion of so-lar light, which can exhibit maximally achievable efficiency of energy conversion compared with other solar energy utilization technologies.
