Desired properties for a solar cell

Click For Summary
SUMMARY

Silicon, Germanium, and Gallium are effective materials for solar cell production due to their semiconductor properties, while Platinum, being a conductor, is unsuitable for this application. The discussion highlights the importance of semiconductor materials in solar cells, particularly in relation to their threshold frequency, which is critical for photon absorption and electron excitation. The inability of Platinum to function as a semiconductor is a key reason for its exclusion in solar cell manufacturing.

PREREQUISITES
  • Understanding of semiconductor physics
  • Knowledge of solar cell technology
  • Familiarity with threshold frequency concepts
  • Basic principles of electrical conductivity
NEXT STEPS
  • Research the properties of semiconductor materials used in solar cells
  • Explore the role of threshold frequency in photon absorption
  • Study the differences between conductors and semiconductors
  • Investigate advancements in solar cell technology and materials
USEFUL FOR

Researchers, materials scientists, and engineers interested in solar energy technology and the properties of materials used in photovoltaic applications.

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? :smile:
 
It is a conductor. But why do we need semi-conductors?
 
Thanks a lot!
