Large area module performance and identification and control of p-i interface-correlated device degradation and further improvement in stabilized efficiencies of single-junction a-Si solar cells
- Advanced Photovoltaic Systems, Inc., San Bruno, CA (United States)
On a large scale, APS` PVUSA array has been in operation for two years now and continues to produce power in excess of its original specifications. Its output measured in october, 1994 was 423 kW{sub AC}. On a laboratory scale, in the last IEEE PVSC the authors reported progress in improving the stability of a-Si based solar cells and in establishing 7.7% stabilized efficiency in single-junction devices. The best of these devices had a relatively low Voc of about 0.8 volts. By further optimization of the p layer, and p-i interface they have produced single junction devices with 0.86 volt Voc and 8.5% stabilized efficiency. Stable output in these devices was obtained after a very brief, 10 hour light soak.
