Abstract

We studied the effect of high-intensity light-soaking on the quantum efficiency spectrum of textured a-Si:H solar cells. We report experimental results on the time, temperature, and soaking light intensity dependence of the quantum efficiency (QE) measured in short circuit. Under 3Wcm-2 of white light the QE saturates after 30 minutes. The QE decays little in the blue and strongly in the red. The higher the temperature of saturation, the smaller the decay of the QE.
