Progress towards modelling solar spectral radiation for optimisation of amorphous silicon photovoltaic systems

This paper presents development work on a tool for modelling the spectrum of incoming solar radiation for application to predict the seasonal change in efficiency of thin film amorphous silicon photovoltaic devices due to spectral shift. The work is based on NREL's SPCTRAL2 model for clear skies. Development work on the original model includes modification of the aerosol model with UK measurements and extended work on the Nann/Riordan cloud cover modifier method to operate satisfactorily in cloudy conditions. The model is implemented in Borland Delphi 5.0 and requires only standard meteorological data for input to generate the solar spectrum from 300 to 1700 nm. The model has been validated in Loughborough, UK against spectral measurements from the spectroradiometer at CREST.
