Testing for Si Solar Cells Using High Performance CCD
EL Imaging Tester
-
EL Testing for Si Solar Cells using High Performance CCD. The determination of luminescence (photo emissions) in solar cells is an important characterization tool. Typical solar cells often have defects which limit the efficiency or lifetime of a cell. Many of these defects are visualized with Luminescence Imaging. By using this technique, the manufacturing process can be optimized to produce better cells. Luminescence Imaging takes advantage of the radiative inter-band recombination of excited charge carriers in solar cells. The emitted photons can be captured with a sensitive CCD camera to obtain an image of the distribution of the radiative recombination in the cell. This distribution is determined by the local excitation level, allowing the detection of electrical losses, thus mapping the diffusion length of minority carriers as the emitted light is low intensity and in the near infra-red range, the CCD camera has a high sensitivity wavelength from 900 to 1100 nm with little thermal noise. This CCD camera provides excellent resolution of 1024 x 1024 pixels with a large 1μm pixel size, multi-megahertz readout speed, and robust USB 2.0 connectivity. The EL CCD Camera is the ultimate high-performance CCD camera for electroluminescence and photoluminescence imaging for Photovoltaic (PV) Cells and Modules. This camera combines low noise electronics and optimal sensitivity in NIR.

CCCP is the technology behind Nüvü Camēras’ extraordinary sensitivity in low light imaging. The patented controller generates significantly less clock-induced charges (CIC) than any other CCD controller during charge transfer throughout the EMCCD (down to an average below 0.001 ē/pixel/frame), therefore allowing for greater EM gain to ultimately attain sub-electron readout noise.

Dynamic Calibration for ROSS Streak Cameras
DynaCal
-
The DynaCal Optical Calibration Module (OCM) is designed exclusively for the Sydor ROSS Streak Camera to ensure accuracy, both over time and in situ, so you can be confident that the data from your shot is certified to be correlated to the calibration of your camera. The beauty of in situ calibration is that the cost of removing and resetting the camera is avoided—and so is the risk of the replacement of the camera and shifting or disturbing the sensitive nature of streak camera results. Only in situ calibration will reveal the real world effects of EMR, gravity, electronic noise and more when they distort your camera results.

National RF’s Type HFDF high frequency location system is a proven noise hunting and location directional antenna system that allows you, in many cases, to walk right up to the source of High Frequency (HF) noise! Used by several power companies around the United States, professional noise hunters, and other communications specialists, the HFDF has located noise sources that emanated from pole power transformers, arcing electric fences, CATV in-line amplifiers, plasma TV screens, and even Marijuana grower’s heating lamps! The system incorporates several plug-in, tunable magnetic loop sensors of a proprietary National RF design, that cover the frequency range between 1.8 MHz and 55 MHz. The unit is packaged in a hand-held, lightweight metallic enclosure, with a pistol grip and a magnetic compass mounted on top. The compass is used to get magnetic bearings to the noise source, which may be plotted on a map to triangulate, and ultimately pin-point, the location of the noise source. In certain cases, our customers tell us that they have been able to walk right up to the interfering noise source and correct the situation on the spot!
