Planks Constant Apparatus using Solar Cell
Product Code : EL-LE-12127
Eduscope India is a leading Planks Constant Apparatus using Solar Cell
Quick Answer: The Planks Constant Apparatus using Solar Cell demonstrates how the photon energy given by the Einstein equation equals the energy gap between the valence and conduction bands, using a diode junction setup.
As a physics lab equipment India resource for modern-physics teaching, the apparatus shows how the energy gap is equal to the energy barrier that electrons must overcome moving from the n-doped side of a diode junction to the p-doped side when no external voltage is applied; on the p-doped side, electrons recombine with holes, releasing that energy in the form of a photon - the basis for determining Planck's constant experimentally.
