Gallery: NREL’s Silicon Wafer Screening System Could Save Solar Industr...


Used in the manufacturing of solar cells, silicon wafers are an integral component that also create a sizable financial loss for the solar industry. About 5-10 percent of wafers get damaged during the production process, increasing the final cost of installed solar systems by billions of dollars each year. In an attempt to improve the efficiency of solar manufacturing, researchers at the National Renewable Energy Laboratory (NREL) have developed a device that detects weak or defective wafers before they reach the solar cell production stage.
