Novel NIST Laser System Mimics Sunlight to Test Solar Cell Efficiency

Caption

NIST engineer Tasshi Dennis is shown with NIST's solar simulator based on a white light laser. The instrument simulates sunlight to help measure the properties of solar cell materials. The instrument's beam is illuminating a gallium arsenide solar cell (yellow diamond) in the lower left corner of the photo.
