Planks Constant Apparatus using Solar Cell
Product Code : EDS-LE-12127 Planks Constant Apparatus using Solar Cell
Description
The photon energy by Einstein equation E=hn is equal to energy gap Eg between the valence and conduction bands.
The energy Eg is equal to the energy barrier eV0, that electron have to overcome in going from n-doped side of diode junction to p-doped side when no external voltage V is applied to the diode.
In the p-doped side, electron recombine with holes releasing the energy Eg in the form of photon is given by equation
