Generally, solar cells on the market today do not produce much electricity from ultraviolet light, instead it is either filtered out or absorbed by the cell, heating the cell. That heat is wasted energy and could even lead to damage to the cell. However, researchers at the University of Illinois have discovered a way to utilize that energy by placing a film of silicon nanoparticles onto the silicon solar cell. By diluting particles of silicon in alcohol, covering a solar cell with it and letting
Again, as we pointed out in a previous posting, solar power is likely the most environmentally source of power available, but there are problems associated with it. Currently, solar cells are not cheap enough, nor are they powerful enough to replace much of our existing power generation methods.
