ABSTRACTWe 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.

AbstractWe study the effect of illumination intensity on solar cell performance in a-Si:H solar cells. We find that the fill factor strongly depends on light intensity. As we increase the illumination intensity from low levels to one sun we observe a decrease in fill factor of approximately 15% in as grown cells. We attribute this effect to electric field collapse inside the cell. We propose that photogenerated space charge (free and trapped charge) increases with light intensity and causes field collapse. We describe the origin of space charge and the associated capacitance - photocapacitance. We measure the photocapacitance as a barometer to probe the collapsed field. We obtain a good agreement between photocapacitance experiments and theory. We also explore the light intensity dependence of photocapacitance and explain the decrease of FF with the increasing light intensity.
