Solar energy, as the largest renewable energy source globally, is developing rapidly. However, the accumulation of dirt on solar panels can severely impact their efficiency. Given the vast number of panels in photovoltaic power stations, regular cleaning is not only time-consuming but also labor-intensive. Therefore, the development of “self-cleaning” technology has become an ideal solution.

In response, scientists worldwide are actively conducting related research. Recently, Hong Kong startup SAMBO introduced a hydrophilic self-cleaning nano coating designed to mitigate potential material degradation and reduce cleaning costs for photovoltaic stations in both dry and humid environments.
