7th-Grader Designs Three Dimensional Solar Cell 719
Hugh Pickens writes "12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light has won him an award and a $25,000 scholarship from the Davidson Institute for Talent Development. 'Current solar cells are flat and can only absorb visible light'" Yuan said. 'I came up with an innovative solar cell that absorbs both visible and UV light. My project focused on finding the optimum solar cell to further increase the light absorption and efficiency and design a nanotube for light-electricity conversion efficiency.' Solar panels with his 3D cells would provide 500 times more light absorption than commercially-available solar cells and nine times more than cutting-edge 3D solar cells. 'My next step is to talk to manufacturers to see if they will build a working prototype,' Yuan said. "If the design works in a real test stage, I want to find a company to manufacture and market it.""
