Phosphor Powder for solar cells

Click For Summary
SUMMARY

Phosphor powders do not emit electrons when struck by light; instead, they emit photons after being excited by photons within specific light bands. This characteristic makes phosphor powders unsuitable for direct electron emission in solar cells. The discussion highlights the misconception regarding the behavior of phosphors in relation to light interaction, emphasizing the importance of understanding photon emission in the context of solar energy applications.

PREREQUISITES
  • Understanding of photon and electron behavior in materials
  • Basic knowledge of solar cell technology
  • Familiarity with phosphor materials and their applications
  • Concepts of light excitation and emission spectra
NEXT STEPS
  • Research the properties of phosphor powders in detail
  • Explore the mechanisms of photon emission in materials
  • Study the design and efficiency of solar cells
  • Investigate alternative materials for electron emission in solar technology
USEFUL FOR

Researchers in materials science, solar energy engineers, and anyone interested in the application of phosphor powders in energy technologies.

someone just asked this as a comment on an article i was reading

http://home.howstuffworks.com/fluorescent-lamp6.htm

'Does a phosphor powder give off a photon or electron when struck by light?'

I was just thinking maybe a solar cell made of phosphor powder to emit electrons.

I failed chemistry at uni so yea =/, the answer might be obvious but i'd have no idea.

No, phosphors do not give off electrons when struck by light. However, phosphors do emit photons after being struck by other photons (within certain bands of light).
