Research on amorphous silicon based thin film photovoltaic devices: Task B, Research on stable high-efficiency, large area amorphous silicon based submodules
- Chronar Corp., Princeton, NJ (USA)
This report describes a project to develop amorphous silicon p-i-n/p-i-n tandem junction photovoltaic submodules with an aperture-area efficiency of at least 9%. A second objective was to demonstrate 8%-efficient tandem submodules that degrade by no more than 5% under standard light-soaking conditions. Improved deposition conditions were established for tandem cells; the resulting efficiencies were nearly as high as those for single-junction cells. An amorphous silicon tandem cell (1 ft{sup 2}) was fabricated with an aperture-area efficiency of 7.2%. Also, good outdoor stability was observed for a glass-encapsulated tandem submodule. Also produced (by magnetron sputtering) were high-quality doped zinc-oxide films (5 ohms/square). 12 refs., 30 figs., 10 tabs.
