Abstract
We investigate in detail the creation of mestastable dangling bond defects in undoped hydrogenated amorphous silicon by illumination with pulsed-light sources. Based on the electron-hole recombination model for defect creation, the kinetics of the defect generation process is analyzed theoretically for different experimental conditions (pulse length, pulse energy, repetition rate, and average intensity). These theoretical results are then compared to experimental observations using both monochromatic and polychromatic (''white light'') pulse sources. Implications of pulse illumination for accelerated testing of the stability of amorphous-silicon-based solar cells are also discussed.
