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.
Fuel cells vs solar panels.
Hydrogen fuel and.
The fuel cell efficiency is 36 32 with dissipation after electrolysis under a 60w light bulb and is 40 04 with dissipation after electrolysis under the sun.
10 s or a 100 times more.
The solar cell provides essentially free energy.
The solar cell efficiency is 15 33 under a 60 watt incandescent light bulb and is 15 13 under the sun.
Fuel cells can generate a great deal more power.
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.
The fuel cell does not.
Solar cells convert light into electrical energy.
A fuel cell uses hydrogen or hydrogen rich fuels to convert hydrogen.
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.
