Background

With the increase of energy consumption, the development of a technology for efficiently utilizing solar energy has great significance. At present, technologies such as photovoltaic, photo-thermal power generation, photochemistry and the like are mainly used for utilizing solar energy.

The photovoltaic power generation technology mainly utilizes the photovoltaic effect of a semiconductor interface in a photovoltaic panel to convert light energy into electric energy. In summer, the temperature of the photovoltaic panel rises sharply due to high illumination and radiation intensity, so that the photovoltaic power generation efficiency is reduced; in winter or severe cold areas, the temperature of the photovoltaic panel is reduced, the photovoltaic power generation efficiency is affected, and in some areas, the difference between the daytime temperature and the night temperature is too large, so that the photovoltaic module is adversely affected.

The photo-isomerism technology is that solar photons irradiate organic molecules with photoresponse to enable the organic molecules to generate isomerism reaction, and a low-energy stable structure is converted into a high-energy metastable state structure. The process directly stores solar energy in chemical bonds, and reduces loss caused by multiple energy conversion.

Compared with the traditional phase change material, the photochemical heat energy has high density which is several times higher than that of the traditional phase change material, and can absorb ultraviolet rays and improve the utilization range of solar spectrum.

However, the photovoltaic power generation technology or the photochemical technology is only used for a part of wave bands in the spectrum of the sunlight by single use, and the rest wave bands are not used, so that the utilization range of the sunlight is limited.
