Voltage-dependent quantum efficiency measurements of amorphous silicon multi-junction mini-modules

Multi-junction solar cells have the potential to provide higher efficiencies than single junction devices and to reduce the impact of Staebler-Wronski degradation on amorphous silicon (a-Si)devices. They could, therefore, reduce the cost of solar electricity. However, their characterization presents additional challenges over that of single junction devices. Achieving acceptable accuracy of any current-voltage calibration requires correction of the current-voltage data with external quantum efficiency measurements and spectral mismatch calculations. This paper presents voltage dependant EQE curves for both single junction and double junction a-Si solar cells, along with dispersion curves extracted from these data. In the case of single junction a-Si devices the mismatch factor is known to be voltage dependent and a similar trend is shown to apply to multi-junction devices as well. However, the error introduced into current voltage calibrations due to this bias dependence is found to be < 1% for spectral mismatch calculations

Framework for a Comparative Accelerated Testing Standard for PV Modules: Preprint

As the photovoltaic industry has grown, the interest in comparative accelerated testing has also grown. Private test labs offer testing services that apply greater stress than the standard qualification tests as tools for differentiating products and for gaining increased confidence in long-term PV investments. While the value of a single international standard for comparative accelerated testing is widely acknowledged, the development of a consensus is difficult. This paper strives to identify a technical basis for a comparative standard
