What is the approximate open-circuit voltage from a fully illuminated silicon photovoltaic cell?
0.02 VDC
0.5 VDC✓پاسخ درست
0.2 VDC
1.38 VDC
توضیح
The open-circuit voltage of a photovoltaic cell is set by the semiconductor's band gap and the junction physics, and for silicon that comes out at roughly 0.5 to 0.6 volts per cell in full sun. It does not depend on the cell's physical area, which sets current instead.
