Desired properties for a solar cell

[Shivansh Mathur]

Elements like Silicon, Germanium and Gallium can be used to make solar cells but platinum can not be used.
What is the exact reason? Is it related to threshold frequency?

Tried to search for the answer through many sources, but couldn't get a satisfactory one.
Your views and answers are really appreciated.

Thanks in advance

Welcome to the PF.

Is Platinum a semiconductor or a conductor?

 

[Shivansh Mathur]

It is a conductor. But why do we need semi-conductors?
