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.

Linear Array
Linear array sensors consist of a linear array of integrating photosensing pixels which measure incident light over a user-defined exposure time and generate a voltage or digital output which represents the light exposure at each pixel. The sensors are available in a variety of lengths and pixel resolutions. The analog output may be directly interfaced to an ADC for digital processing or for comparing black/white thresholds. Applications include contact image sensing, optical character recognition, edge detection, and object measurement in products such as copiers, document scanners and spectroscopy.

Solar Simulator for Multijunction Solar Cells
For series connected multijunction cells, at a given spectrum (e.g. AM 1.5 or AM 0 for space solar cells), one of the cells will limit the current in the series connection of cells. All solar simulators deviate from the true AM 1.5 spectrum, and they are only classified in wide spectral bands (100nm width). So even for class A or A+ solar simulators, it can easily happen that the bandgaps of the multijunction cells are such distributed that the 'wrong' cell will limit the current, if a solar simulator with fixed spectrum is used. In the 70s and 80s, when these measurements were first developed, intercomparisons showed deviations of cell efficiency in fixed spectrum solar simulators of more than 40%.
