An Alternative Method for Spectral Response Measurements of Large-area Thin Film Photovoltaic Modules
A new method for the spectral response measurement of large‐area single and multi‐junction thin‐film photovoltaic
modules is presented, making use of a chopped monochromatic beam produced from a continuous source with band pass
filters and lock‐in technique. The beam is projected onto part of the test module and superimposed over continuous bias
light of variable colour. The procedure for the determination of the absolute spectral response is presented, and the
influence of the intrinsic non‐uniformity of the monochromatic beam is investigated. The results obtained are compared
with those from two other methods of spectral response measurement, providing a validation of the proposed experimental
setup.
