Micro-nano Photoelectric imaging measurement system uses microscopic imaging technique, multi excitation light paths, to provide stable, little size monochromatic light to a photovoltaic test device. Its functions are characterizing the short-circuit current distributions, surface defect, and reflectivity in electronic devices. Based on the galvo scanning technique, the system features fast scanning and high spatial resolution, widely used to research solar cells and photoelectric devices, such as Dye sensitized, monocrystal silicon, multicrystal silicon, organic semiconductor, GaN detector, and so on. The photoelectric imaging can provide important analytic data for the QE, the resistance distribution, and the inhomogeneity of photo-generated current. System Structure: The system contains excitation lasers, scanning galvanometer, microscopy, data acquisition unit, and control software. When scanning the sample, the galvanometer make the laser spot scans and moves in the XY direction of the sample fast. The software records the position of each scanning point and current output value, and synchronously depicts a graph showing the current distribution of the sample. The light path also ensure the light spot pattern on different positions of the sample will not change. Components: ■ Light Sources ■ Microscopy ■ Scanning Galvanometer ■ Source Meter ■ Probe Station and Software Features ■ Multi-laser wavelength is optional ■ Easy sample replacement ■ XY linear stage is easy to change the measuring point of the sample ■ Galvo scanning removes the vibration effects ■ The visualization software can arbitrarily choose the scanning area
