SUMMARY

The discussion clarifies the distinction between photo-conductive and photo-voltaic devices. Photo-conductive devices alter their conductivity in response to light exposure, while photo-voltaic devices generate electrical power through voltage induced by electromagnetic radiation (EMR). Both types rely on the movement of charge carriers, but their functional outcomes differ significantly. Understanding these differences is crucial for applications in electronics and renewable energy technologies.

PREREQUISITES
  • Basic understanding of semiconductor physics
  • Familiarity with electromagnetic radiation (EMR)
  • Knowledge of charge carrier dynamics
  • Awareness of electrical conductivity principles
NEXT STEPS
  • Research the principles of semiconductor physics in detail
  • Explore the mechanisms of electromagnetic radiation and its interaction with materials
  • Study the applications of photo-voltaic devices in renewable energy
  • Investigate advancements in photo-conductive materials and their uses
USEFUL FOR

Electronics engineers, renewable energy researchers, and students studying semiconductor technology will benefit from this discussion.

I am geting confused ( :confused: ) that what is the difference between photo-conductive and photo-voltic devices.

as boath devices depends on the intensity of light, boath depends on no of charge cariers,...
In boath cases there is movement of charge cariers , so there is a flow of current, then what is the difference :(
 
Physics news on Phys.org
Imho the difference you are looking for is that photoconductive devices only change their conductivity when exposed to light while photovoltaics actually generate electrical power by the means of voltage induced by EMR.
 
hmmmm thanks , its looking right ans thanks , :)
