Can solar-thermal phase change composites harness solar energy?

To clarify future research directions, this study first analyzes the heat transfer process of solar-thermal conversion and then reviews solar-thermal phase change composites for high-efficiency harnessing solar energy. The focus is on enhancing heat absorption and conduction while aiming to suppress reflection, radiation, and convection.

Can a microencapsulated phase change material be used for solar-thermal-electric conversion?

Solar-thermal-electric conversion shows great promise, especially in off-grid aerospace and navigation. However, low output density and intermittency of solar energy limit its application. Herein, a microencapsulated phase change material (MPCMs) is designed with a n-Tetracosane core and TiO 2 /Ti 2 O 3 composite shell to address the above issue.

What is a microencapsulated phase change material (mpcm)?

Herein, a microencapsulated phase change material (MPCMs) is designed with a n-Tetracosane core and TiO 2 /Ti 2 O 3 composite shell to address the above issue. The MPCM exhibits a latent heat of 144.5 J g −1, a photothermal conversion efficiency of 93.7% and 100% energy storage capacity.

How efficient is solar-thermal conversion?

In the current research, the best results show that the solar-thermal conversion efficiency has approached the theoretical limit (100%), and a typical thermal conductivity has reached 33.5 W/ (m·K). However, further enhancement of the absorption and conduction remains a challenge, highlighting the need for structural modifications and grafting.

Can multifunctional materials be used to develop all-day solar-thermal-electric power generation technology?
