Extra exam question E6F11
Subelement E6, CIRCUIT COMPONENTS· Group E6F
What is the approximate open-circuit voltage produced by a fully illuminated silicon photovoltaic cell?
- A.0.5 volts (correct answer)
- B.0.7 volts
- C.1.1 volts
- D.1.5 volts
WhyA fully illuminated silicon photovoltaic cell produces an approximate open-circuit voltage of 0.5 volts. A fully illuminated silicon photovoltaic cell produces an open-circuit voltage of roughly 0.5 volts, a figure set by the underlying silicon PN junction's characteristics, answer A. The higher figures of 0.7, 1.1, and 1.5 volts don't match a single silicon cell's typical open-circuit output under full illumination.
