Coloured building integrated photovoltaics: Influence on energy ...
The energy generation is modelled by calculating the short circuit photocurrent density J sc as [33]: (15) J s c = ∫ 300 1200 q λ h c (1 − A (λ) − R (λ)) I (λ) I Q E (λ) d λ where I(λ) is the AM1.5 G standard solar irradiance spectrum, IQE(λ) is the internal quantum efficiency, q is the electron charge, λ/hc is the photon energy, R(λ) is the total …
