Scientists working on a joint project have devised a pretty cool way to make solar panels self-cleaning and produce more power. By adding a nanoscopic pattern to the surface of the solar cells, they found that not only does the pattern make the cells non-reflective (which boosts the power output of the cell), it also makes the surface of the cell non-stick and self-cleaning.
The researchers, part of a joint project between Changchun University of Science and Technology (China), Xi’an Technological University (China), and Cardiff University (UK), developed the tiny pattern, which traps sunlight in the cell instead of reflecting it back out. The etched nano sized pattern also makes the cell behave much like a water-repellent lotus leaf – nothing sticks to it, and when it rains, any dust, dirt, bird droppings, etc just get washed off.
