Abstract
This report examines manufacturing multiple-band-gap, multiple- junction solar cells and photovoltaic modules. Amorphous silicon alloy material is deposited (using microwave plasma-assisted chemical vapor deposition) on a stainless-steel substrate using a roll-to-roll process that is continuous and automated. Rapid thermal equilibration of the metal substrate allows rapid throughput of large-areadevices in smaller production machines. Potential improvements in the design, deposition, and module fabrication process are described. Problems are also discussed that could impede using these potential improvements. Energy Conversion Devices, Inc. (ECD) proposes cost and time estimates for investigating and solving these problems. Manufacturing modules for less than $1.00 per peak watt andstable module efficiencies of greater than 10% are near-term goals proposed by ECD. 18 refs.
