With SunShot funding, 1366 Technologies developed these three-dimensional silicon wafers that require fewer raw materials, helping to reduce the cost of solar panels.
EERE Success Story – Silicon Solar Wafers Enter a New Dimension

The vast majority of solar modules are currently made with silicon, as the material is widely available, relatively low-cost, and able to reach high efficiencies. Today, nearly all silicon wafers for solar modules are manufactured by first transforming the raw material into silicon blocks, which are then sawed into thin wafers that are turned into solar cells and integrated into modules. But one SunShot Initiative awardee has developed a method that is changing the game.

EERE Success Story—New Advanced Refrigeration Technology Provides Clean Energy, Low Utility Bills for Supermarkets

Traditional supermarket refrigeration systems found in most U.S. grocery stores require a substantial amount of energy to keep fruits and vegetables fresh year round. An average supermarket consumes nearly 2 million kilowatt hours per year, and refrigeration accounts for nearly half of that. They are also prone to significant refrigerant leakage—20 to 25% leakage a year of the two to four thousand pound refrigerant inventory—emitting environmentally harmful greenhouse gases into the atmosphere.
