Nanotechnology solution for photovoltaic systems

Photovoltaic (PV) systems, which harvest sustainable and clean energy from the sun, accumulate dirt or particles like dust, water and sand. This build-up leads to a reduction in the light energy reaching the solar cells and lowers their power output by up to 50%, according to some studies. Therefore, it's crucial to keep them clean. However, the process of regular cleaning and maintenance could be costly and also waste water.
