Subsequently, this DOS is illuminated in relation to the electric field vector [1, 40,
41]. In A curtain wall skins and B, the cooling photon DOS shows a pure anti-logarithmic anti-divergence next to the PBE, which is estimated as ϱ PC (ω) ∝  − [ln|(ω − 
ω 0 )/ω 0 | − 1]Θ(ω − ω e ), whereby ω e exemplifies the peak’s central point in the distribution of DOS.
As aforementioned, J(ω) describes the DOS field manufactured in the PV cell
with the fine cooling photonic magnitude V(ω) in the PV cell and the PB [7, 22]:

Henceforth, I deliberate the PB frequency ω c and the proliferative photon dynamics ⟨a(t)⟩ = u(t, t 0 )⟨a(t 0 )⟩, whereby the function u(t, t 0 ) describes the photon structure. u(t, t 0 ) is computed with the use of the dissipative integral–differential equation

at different DOS in A, B, and C curtain wall. The frequencies of photon module magnitudes to
discharge energy computed by Eq. (5.2) taking into account the state illustrate the moment frequency vc transmuted through a PBG field to a PB area [36, 37]
