WebbA general description of the cell unit size of the various cases is found below: 1. The first cell unit: In the cell of the first unit, the number of atoms in a unit is equal to one. Therefore, the size is given by: Maximum cell unit = 1 × Ma3 × NA 2. WebbConsequently, differentiating the above equation will give the generation at any point in the device. Hence: G = α N 0 e − α x where N0 = photon flux at the surface (photons/unit-area/sec.); α = absorption coefficient; and x = distance into the material.
