What is the approximate open-circuit voltage from a fully illuminated silicon photovoltaic cell?
Pick an answer to check it.
Answer: B. 0.5 VDC
A fully illuminated silicon photovoltaic cell produces about 0.5 volts DC with no load. That is why many cells must be connected in series to make a useful panel voltage.
Tip: Silicon cell: about half a volt.
