Question

Photovoltaic solar panels are manufactured from -

• A. Carbon
• B. Silver
• C. Silicon
• D. Germanium

Hint:

Silicon's efficiency and abundance make it the most widely used material in photovoltaic solar panel technology.

Answer 1

The Correct Option is C

Photovoltaic solar panels are primarily made from Silicon, a semiconductor material. Silicon is used because of its efficient ability to convert sunlight into electricity through the photovoltaic effect. While other materials like carbon and germanium have also been explored, silicon remains the most widely used material in the production of solar panels.
Step 1: Analyze the options.
(A) Carbon: While carbon-based materials like graphene are under research for future solar technologies, carbon itself is not commonly used in current photovoltaic solar panels.
(B) Silver: Silver is used in solar cells for electrical contacts but is not the primary material in the construction of the solar panel itself.
(C) Silicon: This is the correct answer. Silicon is the most commonly used material in photovoltaic solar panels due to its excellent semiconductor properties.
(D) Germanium: Germanium was historically used in solar cells but has largely been replaced by silicon in modern photovoltaic technology.
Step 2: Conclusion.
Silicon is the primary material used to manufacture photovoltaic solar panels, making (C) the correct answer.
Final Answer: \[ \boxed{(C) \, \text{Silicon}} \]
