Crazy! 12-Year Old Boy Will Save the World! His Solar Cell Absorbs 500 Times the Light of Existing Cells.
In his project “A Highly-Efficient 3-Dimensional Nanotube Solar Cell for Visible and UV Light,” William invented a novel solar panel that enables light absorption from visible to ultraviolet light. He designed carbon nanotubes to overcome the barriers of electron movement, doubling the light-electricity conversion efficiency. William also developed a model for solar towers and a computer program to simulate and optimize the tower parameters. His optimized design provides 500 times more light absorption than commercially-available solar cells and nine times more than the cutting-edge, three dimensional solar cell.
