Using a few spectral wavelengths to enhance short circuit current predictions in PV performance models

Lave, Matthew S.; Hansen, Clifford H.; Ueda, Yuzuru; Hakuta, Keiichiro

Short circuit current (Isc) depends on the effective irradiance incident upon a PV module. Effective irradiance is highly correlated with broadband irradiance, but can vary slightly as the spectral content of the incident light changes. We explore using a few spectral wavelengths with broadband irradiance to predict Isc for ten modules of varying technologies (silicon, CIGS, CdTe). The goal is to identify a few spectral wavelengths that could be easily (and economically) measured to improve PV performance modeling.
