The utility model relates to a photovoltaic module with self -cleaning function, photovoltaic module's local sensitive surface coating has super hydrophilic coating. The utility model discloses a photovoltaic module with self -cleaning function drops on super hydrophilic coating surface when the water droplet and the time can expand into the water film rapidly, makes filth such as dust floated on the photovoltaic module surface, and then is walked by the water -washed more easily, not only can reduce reflection and the absorption of super hydrophilic coating to the sunlight to reduce photovoltaic module's power loss. The space can also be left for super hydrophilic coating's thermal energy, the long -term chappy possibility of back coating of using is reduced. Can also reduce the use amount of coating to reduce photovoltaic module's manufacturing cost. 本实用新型涉及种具有自洁功能的光伏组件，光伏组件的局部受光面涂覆有超亲水涂层。本实用新型的具有自洁功能的光伏组件，当水滴落在超亲水涂层表面时会迅速扩展成水膜，使灰尘等污物在光伏组件表面被浮起，进而较容易被水冲走，不仅可以减少超亲水涂层对太阳光的反射和吸收，从而减小光伏组件的功率损失。还能为超亲水涂层的热膨胀留有空间，
