Hydrogen could produce solar panels.

Breakthroughs areCALIFORNIA researchers always on the lookout for the next great technology, renewable energy.
To an engineer who thought Duke University have a new system of hybrid solar as fuel which produce energy much more efficiently than current technology.
Nico Hotz, Assistant Professor of mechanical engineering and materials science, developed a system, the sunlight is used to heat a combination of water and methanol in a maze of pipes and tubes of glass on the roof.
The collection of solar thermal hybrid looks like traditional heat collectors. But is actually a series of copper pipes are covered with a thin layer of aluminium and alumina. Then placed in a vacuum and is filled with a combination of water, methanol and catalyst (substance that speeds up a chemical reaction at a given temperature) nanoparticles.
Hotz explains that this design is capable of 95 percent of the sunlight reaches a temperature of more than 200 degrees Celsius absorb that can be stored in the tube. The standard for comparison with hot water boil between 60 and 70 degrees Celsius.
Also added some catalyst to produce hydrogen. Hydrogen could be addressed then to these cells, to supply electricity directly used during the day or compressed and stored in a generation before, that want the user can be used.
With team compare Hotz and hybrid systems, solar cells and other systems, it turns out that this hybrid system has a better 3 Keuanggulan. The solar cells, which can change the standard which is sunlight directly into electricity, then it can also change the mix water into hydrogen and oxygen, or first such a system has a photovoltaic (PV) cell.
Not only that the PV cells are capable of converting solar energy into electricity, then you can keep it in lithium-ion batteries, but this is a simple system of solar cells.
The results of this analysis has been published on Hotz Conference ASME energy sustainability fuel cell 2011 in Washington, D.C.
