Solar energy becomes commonplace. It is of what lets think the unveiling of the plant of photovoltaic cells of Konarka, in the Massachusetts (United States). An ancient photographic plant of films given up by Polaroid before being re-conditioned to produce every year thousand megawatts of plastic solar cells. Because, contrary to most technologies produced as a whole, [...]
To fabricate solar cells outside, without the ultra-sophisticated techniques of preparation of materials semidrivers? Mean, told themselves four Danish researchers and German who introduce their method in the magazine Nanotechnology. A method which is almost recovering from the kitchen, since it leans on a mixture of nanoparticles of oxide of zinc and of a polymer which, [...]
The hydrogen? Many people speak about it as «the energy of future». The rumour-mongers pretend that she will remain him. They are perhaps wrong. Because two jobs published on Friday in the magazine Science show that the manufacture of hydrogen from solar energy is not any more an Utopia.
Today, the industrial hydrogen is obtained by splitting hydrocarbons. What makes that cars [...]
The solar cells, this walks since the sixties. But because of their weak output and of their cost price, to cross the threshold of competitiveness returns to climb up an impassable mountain. The American Nanosolar had opened a way in producer of cells hundred slimmer times. Researchers of the Massachusetts Institute of technology have [...]
In the United States, the stories of start-up begin often just like that. Teachers, idea, and motivated students. It is just like that that Raw-Solar, the young shoot was born who pretends to revolutionise the solar production of heat with high temperature. A direct emanation of jobs driven by the students in the Massachusetts Institute of Technology, who created [...]
Solar energy has the wind in poop in the United States. And it is not the study published by the Solar Catalyst Group and Klin Edge who will deny him. The experts think that the United States could draw 10 % of their electricity of the sun in 2025, by combining the photovoltaic installations and the solar power stations with concentration.
Electrical [...] power
Reduce by a factor 10 the number of cells used in the photovoltaic concentrators (CPV), here is the small revolution offered by the engineers of IBM. Secret: link photovoltaic technology and computer technology. The principle of functioning of CPV is simple: the more light is concentrated on the cell, the more produced electrical power is important. There [...]
