ABSTRACT
Experimental evidence of bond breaking in hydrogenated amorphous Si films is presented, which accounts for the degradation of solar cell performance. For films with prolonged illumination, Fourier transform infrared spectroscopy showed distinct transitions occurring among various bonds, and electron paramagnetic resonance showed dangling bonds being produced. The bond breaking was reversible by thermal annealing.
