Abstract :
An integrated system is described which consists of a spectral radiometer and dual-source solar simulator, and personal computer-based current-voltage and quantum efficiency equipment. The apparatus was used to measure the dependence of the absolute external quantum efficiency of triple-junction a-Si:H alloy solar cells. The cells were measured under AM0 light bias at various forward-bias voltages including the maximum-power point. The quantum efficiencies of the cells were measured with both spectral-light bias and AM0 light bias
