Abstract:
The design and application of a novel, focused solar simulator based on a high-power, super-continuum laser is described. We used the simulator to create micrometer-scale spatial maps of full-spectrum optical beam induced current (FS-OBIC) in sample solar cells. Microscopic details such as grid lines, damage spots, and material variations were selectively excited and spatially resolved. By approaching a diffraction-limited focus, it is anticipated that this unique tool can be effectively used to characterize the detailed operation of solar cell materials and devices at the nanoscale.
