Description

Technical Field

[0001] The present invention relates to the field of solar photovoltaic technology, in particular to a method for preparing an easy-to-clean full-color photoelectric functional material. Background Art

[0002] With the growing global demand for renewable energy, solar photovoltaic technology, as a clean and sustainable energy solution, has become a key technology in the energy structure transformation of many countries and regions. In this context, the design and performance of full-color optoelectronic functional materials not only directly affect energy conversion efficiency but also play a significant role in improving architectural aesthetics and the urban environment. In particular, full-color optoelectronic functional materials, with their vibrant colors and flexible designs, are increasingly favored by consumers in areas such as engineering lighting and landmark architectural displays, becoming a major highlight of modern urban architecture.

[0003] However, existing full-color optoelectronic functional materials face a number of challenges in practical application. First, these components typically achieve their color effects by coating their surfaces with a patterned polymer material. However, this coating has a relatively low hardness and is susceptible to scratches and abrasion from external physical factors. Furthermore, due to the properties of the surface material, these components are highly susceptible to dust and dirt. Over time, dust accumulates on the surface, affecting not only the aesthetics but also the photoelectric conversion efficiency.

[0004] Secondly, in terms of maintenance and cleaning, existing technical solutions mainly rely on manual surface cleaning using brushes, towels and other tools. This method not only requires a large number of personnel and a long cleaning cycle when cleaning large quantities of full-color optoelectronic functional materials, but also has high cleaning costs. What is more serious is that due to the physical friction during the cleaning process, the colored patterns on the surface of the components can easily be scratched, affecting their appearance and service life. For full-color optoelectronic functional materials installed at high places or other dangerous areas, cleaning work is even more difficult, not only inefficient, but also posing a safety hazard.
