  1. INNOVATION Flexible, Lightweight, Amorphous, Silicon Solar Cells Tuned for Air Mass Zero (AMO) Spectrum Small Business Innovation Research Iowa Thin Film Technologies, Inc. Ames, IA Tandem amorphous silicon modules on a polyimide substrate • ACCOMPLISHMENTS • Optical modeling to calculate thicknesses of device layers for maximum AMO solar spectrum absorption • Deposition parameters for device layers optimized for performance of amorphous silicon solar cells in space • Construction of a dedicated tandem amorphous silicon deposition machine • COMMERCIALIZATION • Company sales as a result of SBIR were $200K and growing • ITFT increased from a few employees to 12 full time and 8 part time employees • Phase III monies totaled $4.7M from several government and private sources. The DOE National Renewable Energy Labs (NREL) is the largest government contract. • Private investment provided the financing of a just completed production facility Flexible Amorphous Silicon Modules on a Polyimide Substrate • GOVERNMENT/SCIENCE APPLICATIONS • ITFT amorphous silicon modules for space applications are under evaluation at the NASA JPL • ITFT modules are under evaluation at the NREL/DOE Laboratory for terrestrial applications • Companies evaluating our material for space applications include Lockheed-Martin and TRW, which includes testing in space Lewis Research Center 1989 Phase II, SS#206, 10/97 NASA Contact - Dennis Flood
