Experimental study of the factors governing the Staebler-Wronski photodegradation effect in a-Si:H solar cells : annual subcontract report, 1 April 1995-30 June 1996 by Daxing Han( Book )

4 editions published between 1996 and 1998 in English and held by 7 WorldCat member libraries worldwide

This report describes continuing experiments on electroluminescence (EL), field profile, and H-microstructure studies of a-Si:H-based solar cells and materials. By using EL spectroscopy, we observed that both the band-tail width and the defect energy distribution are narrowed by H-dilution. We demonstrated the existence of the "fast" and "slow" defects in the cell performance and identified their energy positions as a ~0.9 eV and a ~0.75 eV defect EL band. Our results also reinforced the notion that H-dilution eliminates the microstructure that causes the creation of 'slow' defects and hence stabilizes rapidly under light illumination. We demonstrated that the internal-electric field profile of a-Si:H p-i-n structures can be measured by the transient-null-current method. For the first time, hot-wire-deposited a-Si:H films were characterized by 1H nuclear magnetic resonance. Surprisingly, about 90 percent of the H atoms give rise to the 50-kHz line, and only a very small percentage of the H atoms give rise to the 3-kHz-narrower resonance line, which suggests that H-bonding in hot-wire films is very different from that in a-Si:H produced by plasma-enhanced chemical vapor deposition
Microscopic Mechanism of the Staebler-Wronski Effect in a-Si Films and High-Efficiency Solar Cells : Final Subcontract Report, 1 October 2001--30 September 2004( )

1 edition published in 2005 in English and held by 6 WorldCat member libraries worldwide

In high growth rate ({ge} 50 {angstrom}/s) HW-CVD a-Si:H films, for the first time, we show gaseous molecules in nanovoids ({approx}2% volume fraction of tube-like nanoscale voids), and demonstrate that confinement on the nanometer scale generates NMR effects that have never been observed in macroscopic systems. In the same system we found the PL peak red shift. We suggest that highly strained bonds on the inner surfaces of the nanoscale voids form broad conduction-band tail states that are responsible for the PL red shift. We characterized the structural transition from a- to nc-Si as function of H-dilution, thickness and T{sub s} of both HW- and PE-CVD films using IR, Raman, PL, CPM/PDS and E{sub a} et al. We found not only the c-Si volume fraction but also the g.b. and microstructures play an important role in the properties of the i-layer and their solar cell performance. We found a narrow structural transition zone in which the bond-angle variation, {Delta}{Theta}, decreases from 10{sup o} to 8{sup o}. For nc-Si samples, we found a characteristic low energy PL peak and proved that is originated from the g.b. regions. Using micro-Raman, we found the structural non-uniformity in the mixed-phase solar cells that showed V{sub oc} enhancement after light soaking. Using micro-Raman, we also found the slight increase of crystallinity in M/{mu}c-Si/M devices after current forming
Correlation of Structural and Electronic Properties with Solar Cell Efficiency for Amorphous Silicon Deposited at Increasing Growth Rates( )

1 edition published in 2003 in English and held by 6 WorldCat member libraries worldwide

This paper details the effects of increasing the growth rate of hydrogenated amorphous silicon (a-Si:H), deposited by dc plasma chemical vapor deposition, on the structural and electronic properties of the material in comparison with the performance of solar cells incorporating such layers. The hydrogen content exhibits the strongest correlation with the solar cell efficiency. The defect density measured by two different techniques, correlate poorly but when measured by a third technique, correlates well. On the other hand, the Urbach tail slope correlated well when measured by two different techniques but poorly when measured by a third one
