The photocell is similar to:
Correct answer: A. Photoelectric effect
- A. Photoelectric effect
- B. Compton effect
- C. Photoluminescence
- D. None of these options is correct
Explanation
The photoelectric cell, photocell, or photovoltaic cell works on the principle of photoelectric effect. It converts light energy into electrical energy. The energy of photons hitting the semiconductor frees electrons to flow, decreasing the resistance.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
