The team has created an artificial photosynthesis device called a hybrid photoelectrochemical and voltaic hpev cell that turns sunlight and water into two types of energy.
Fuel cells vs solar panels.
Hydrogen fuel and.
Ie a space ship.
Solar cells are best when power without fuel is the most important factor.
This aspect of solar power is evident but the fact that photovoltaics are a technology not a fuel is not.
The solar cell provides essentially free energy.
10 s or a 100 times more.
The fuel cell does not.
Solar cells convert light into electrical energy.
Fuel cells are best when the weight or storage space for the fuel is the absolute most important factor.
A fuel cell uses hydrogen or hydrogen rich fuels to convert hydrogen.
Fuel cells can generate a great deal more power.
While fuels are tangible commodities and must be produced treated and transported solar pv is a technical innovation that involves silicon cells converting sunlight into energy at a highly efficient rate.
