Solar thermal and photovoltaic solar energy development, today's two parallel lines, but the U.S. scientists for the latest scientific research seems to be two parallel lines intersect. According to the American "Popular Science" report, Stanford University engineers have found a few days ago while using the sun's light and heat to produce electricity methods,solar collector which will enable the efficiency of solar energy products meet 3 times the existing methods, and may make solar energy cheap enough to compete and oil.
