Abstract

Molecular solar energy storage technology based on photoresponsive compounds is a unique solar thermal conversion and storage technology. The isomerization performance, energy storage performance and stability of the synthesized tetra-ortho azobenzene molecule were studied experimentally. The results show that the tetra-ortho-azobenzene molecule can undergo isomerization under red, green and ultraviolet light excitation, and its half-life is 70 min at room temperature. The degree of isomerization after red, green and ultraviolet light irradiation is 28%, 41% and 59%, respectively. When the isomerization degree of the tetra-ortho-azobenzene molecule is 100%, its energy storage density is 37.88 kJ/mol. In addition, the tetra-ortho azobenzene molecule exhibits excellent cycle performance and thermal stability.
