Researchers found a new way to make solar power more cheaper and flexible to use. The nano-scale wires built around optical fibres allow more surface area for light to interact with, which improves cell efficiency. Using this technology, photovoltaic generators are foldable, concealable and mobile. Traditionally, silicon based solar cells are most efficient because it absorbs the most light. The new method starts with commerical optical fibre without outer layer and wraps zinc oxide nanowires around the fibre. In addition, light only needs to enter at the ends of the fibre, making it space efficient.
