Photon density formula
WebDec 13, 2024 · To calculate the density of states we just need: 1) The energy of our system. In this case we are dealing with the energy of photons, so: ϵ = ℏ ω. 2) The number of states with energy ≤ ϵ (let's call it N ( ϵ)). As 3 dimensions are considered, the number of states is enclosed in a sphere: N ( ϵ) = 4 3 π R 3. WebAin Shams University. You can calculate the shortcircuit current density Jsc by using the formula: Jsc= Integral over lambda of (EQE (λ)*AM1.5G (λ)*q*λ/h*c)dλ , where: AM1.5G …
