The Sun is not going anywhere for another 4.5 billion years, so photovoltaic cells are here to stay. However, the low conversion efficiency of solar panels is the major obstacle in the exponential growth of this sustainable form of energy. To overcoming the energy storage crisis, scientists are using different techniques and coming up with solutions like biogenic solar cells and wearable solar projects. Sunflowers and tomatoes are the inspiration for the new energy designs. Read further to know about the different materials & methods adopted to exceed the conventional efficiency of solar cells from 13-20% to a whopping 46%.
