What is the approximate open-circuit voltage produced by a fully illuminated silicon photovoltaic cell?
The correct answer is A: 0.5 volts. What is the approximate open-circuit voltage produced by a fully illuminated silicon photovoltaic cell is 0.5 volts. Silicon solar cells produce about 0.5V open-circuit. For amateur radio operators, this is important for photovoltaic knowledge. Understanding this helps when working with solar cells.
Exam Tip
Silicon photovoltaic cell open-circuit voltage = 0.5 volts. Think 'S'ilicon 'P'hotovoltaic = '0'.5V. Silicon solar cells produce about 0.5V open-circuit. Not 0.7V, not 1.1V, not 1.5V - just 0.5 volts.
Memory Aid
"Silicon photovoltaic cell open-circuit voltage = 0.5 volts. Think 'S'ilicon 'P'hotovoltaic = '0'.5V. Silicon solar cells produce about 0.5V open-circuit. Important for photovoltaic knowledge."
Real-World Application
A fully illuminated silicon photovoltaic cell: The approximate open-circuit voltage produced is 0.5 volts. This is why multiple cells are connected in series to get higher voltages. This is the voltage - 0.5 volts open-circuit.
Key Concepts
Why Other Options Are Wrong
Option B (0.7 volts): Incorrect. 0.7V is too high - silicon cells produce about 0.5V open-circuit. 0.7V is wrong.
Option C (1.1 volts): Incorrect. 1.1V is too high - silicon cells produce about 0.5V open-circuit. 1.1V is wrong.
Option D (1.5 volts): Incorrect. 1.5V is too high - silicon cells produce about 0.5V open-circuit. 1.5V is wrong.
