(ScienceDaily, April 12, 2010) — Thanks to two technologies developed by Professor Benoît Marsan and his team at the Université du Québec à Montréal (UQAM) Chemistry Department, the scientific and commercial future of solar cells could be totally transformed. Professor Marsan has come up with solutions for two problems that, for the last twenty years, have been hampering the development of efficient and affordable solar cells. His findings have been published in two scientific journals, the Journal of the American Chemical Society (JACS) and Nature Chemistry. The untapped potential of solar energy – The Earth receives more solar energy in one hour than the entire planet currently consumes in a year. Unfortunately, despite this enormous potential, solar energy is barely exploited. The electricity produced by conventional solar cells, composed of semiconductor materials like silicon, is 5 or 6 times more expensive than from traditional energy sources, such as fossil fuels or hydropower. Over the years, numerous research teams have attempted to develop a solar cell that would be both efficient in terms of energy and inexpensive to produce. Click here to read more…
