Making Our Solar Future with American Manufacturing

Every second that ticks by, six solar cells come off U.S. manufacturing lines that contain crystalline silicon. In 10 years, the Energy Department’s SunShot Initiative expects nearly three-times that amount to be racing across the lines, helping to make America a leader in high-tech solar manufacturing.

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.
