Abstract/Summary:


Two types of the solar simulators were compared in several types of experiments involving crystalline silicon, amorphous silicon solar cells and test structures of transparent oxides and buffer layers used in thin film solar cells. Photo response of solar cells illuminated by commercially available Xenon arc based simulator was used as a benchmark for comparison. Compact light emitting diode (LED) based solar simulator with six LED groups of different colors was the second illumination source in our study. AAA class requirements are met by both solar simulators, but substantial performance differences appear when testing various devices. These differences are attributed to the differences of quantum efficiency spectra of measured devices, surface reflectivity variations for mini-modules and an increase of photo response non-uniformity once the photocurrent contribution is reduced from several diode groups. Numerical calculations for multilayer structures were used for further comparison studies and were employed to clarify the possible origin of the observed phenomena.
