Question

Which metal is used to connect solar cell to solar panels?

• A. Gold
• B. Silver
• C. Copper
• D. Aluminium

Answer 1

The correct option is B Silver

Silver is the best conductor of electricity, therefore it is used to connect solar cells to solar panels.

Gold is not the good conductor of electricity, so it is not used to connect solar cells.

Copper and aluminium are good conductors of electricity but are not used for connecting solar panels. Copper is used for making solar cells and solar panels but not for connecting them.

So the correct option is $B$.
