NREL R&D 100 Award Winners from 1999 through 1982

1999
Advanced Direct-Contact Condenser: A new way of condensing steam that enables geothermal electric plants to generate more electricity more cheaply.
1999
Siemens Solar St-Family of Solar (CIS) Modules: The first large-area solar electric modules made from the promising thin-film material of copper indium diselenide.
1998
UNI-SOLAR Triple-Junction Amorphous-Silicon Solar-Electric Modules: Thin, flexible, waterproof roof shingles that efficiently produce electricity from sunlight.
1998
"Vermont" High-Throughput Gasifier: Turns wood chips into a clean gas for use in fuel cells or gas turbines to produce electricity.
1997
"PV Optics" Software Light-Trapping Model for Solar Cells: Software that enhances and accelerates solar cell designs by modeling how light is absorbed in cell materials.
1997
Chemical Production from Biologically Derived Succinic Acid: Derived from corn syrup (instead of petroleum), this acid is used to make clothes, paints, inks, plastics, and polymers.
1996
Variable-Conductance Insulation Catalytic Converter: A great idea for clean air, this catalytic converter can be used on cars, small trucks, and SUVs to enable them to more than meet EPA's stringent new requirements for emissions.
1995
Method for Making Silicon Carbide Powder: A novel technique for producing fine, pure, inexpensive powder for use in making industrial and electronic ceramic products.
1995
Single-Fermenter Cellulosic Biocatalyst (Zymomonas): This metabolically engineered micro-organism enables the efficient conversion of wood, grass, waste and other cellulose material into ethanol fuel.
1994
Transpired Solar Collector: A simple, elegant idea: a wall siding that uses strategically placed holes to capture solar energy to heat and ventilate buildings.
1993
Ethanol from Corn Fiber: A process that enables the conversion of the carbohydrate portion of corn to ethanol fuel.
1993
Scanning Defect Mapping System: Uses a scanning laser to produce maps of crystal defects in semiconductor materials.
1993
Aqueous Chelating Etch: An innovative etching process used to develop microelectronic circuits, high-temperature superconductors, and opto-electronic devices.
1992
Atomic Processing Microscope: This microscope enables the manipulation of single atoms and allows the properties of materials to be altered on a nanoscale.
1992
Solar Detoxification of Hazardous Organic Materials in Groundwater: Uses sunshine and a simple catalyst to purify contaminated water.
1991
Compact Vacuum Insulation: Very thin material providing extremely high insulation for use in refrigeration, walls, floors — anything that needs to be kept warm or cold.
1991
Gallium Indium Phosphide/Gallium Arsenide Tandem Solar Cell: A light, highly efficient solar cell that has become the world's standard for powering earth-orbiting satellites.
1991
Cadmium Telluride Photovoltaic Modules: The first large-size devices to be made from this new thin-film material, which promises to help drop the cost of solar electricity.
1991
Advanced Wind Turbine Blades: Wind blade designs that have become the industry standard and that produce up to 30% more electricity than previous designs.
1990
Inexpensive Phenol Replacements from Biomass: A process that converts wood chips, sawdust, and bark into an oil for making plastics, glues, insulation, fuels, and chemicals.
1989

1985
Volume-Indexed Secondary Ion Mass Spectrometry: Provides 3-D information about the composition of electronic materials and devices.
1984
Copper Indium Diselenide Solar Cell: The first solar cell to use very thin films (less than the thickness of a human hair) of a promising semiconductor material.
1984
Flash-Evaporation Method/Apparatus (Spout Evaporator): An inexpensive and efficient way to evaporate water to steam, which drives a turbine to generate electricity.
1982
Oxygen High Pressure Gasifier: Uses heat, oxygen, and pressure to turn wood and waste into a gas for generating electricity and heat.
