What is the most common material used in power-generating photovoltaic cells?
The correct answer is B: Silicon. What is the most common material used in power-generating photovoltaic cells is silicon. Silicon is the most common material for solar cells. For amateur radio operators, this is important for photovoltaic knowledge. Understanding this helps when working with solar panels.
Exam Tip
Most common material for power-generating photovoltaic cells = silicon. Think 'P'ower 'P'hotovoltaic = 'S'ilicon. Silicon is the most common material for solar cells. Not selenium, not cadmium sulfide, not indium arsenide - just silicon.
Memory Aid
"Most common material for power-generating photovoltaic cells = silicon. Think 'P'ower 'P'hotovoltaic = 'S'ilicon. Silicon is the most common material for solar cells. Important for photovoltaic knowledge."
Real-World Application
Power-generating photovoltaic cells: The most common material used is silicon. Most commercial solar panels use silicon cells. This is the material - silicon for power-generating photovoltaic cells.
