Hi Everyone,
I'm looking for some help on semiconductor physics, in particular solar cell theory.
In a textbook I have seen that the open-circuit voltage (Voc) of a solar cell is equal to:
Voc = (Eg/e) - 0.80
Where Eg = The optical band gap of the device.
e = Elementary Charge (I assume?)
A solar cell with a 1.6eV band gap (amorphous silicon, for example) seems to have a Voc of around 0.8v, but I cannot get that answer using that formula.
Voc = (1.6/√1.4399764) - 0.8 = 0.53v ?
Any help would be greatly appreciated.
Many Thanks,
Lee
