Breakthrough in photovoltaic technology: 3D graphene
Dye-sensitized solar cells are the best type of solar cells invented so far, but they have a unfavorable aspect: the price. Although they are very thin, pliable, not difficult to make and they have a great conversion rate (8%), they are made from platinum, one of the most expensive elements on Earth. The new inexpensive material that was discovered at Michigan Technological University may replace the platinum used to create these dye-sensitized...
