    CEL-QPCE2030 multi-junction thin film solar cell spectral response system
     
    Introduction:
    The spectral response and quantum efficiency of solar cells have important reference value for analyzing the process problems of solar cells and studying the performance of cell sheets. The CEL-QPCE2030 multi-junction thin-film solar cell spectral performance test system can separately measure the absolute spectral response (Spectral Response) and quantum efficiency (Quantum Efficiency) of the multi-junction thin-film solar cells, and calculate the absolute spectral response of the entire cell. And quantum efficiency. At the same time, the current density of the top and bottom batteries can be calculated separately, as well as the total current density of the battery (under AM1.5G).
     
    Features:
    1) High-power continuous light source, the output spectrum is gentle and has no sharp peaks, ensuring measurement repeatability;
    2) equipped with a bias light source and an offset filter;
    3) Patented spectroscopic system to ensure good wavelength accuracy and repeatability, eliminate the influence of multi-level spectrum, and have small stray light;
    4) The relevant detection method processes the weak signal, effectively improves the signal-to-noise ratio and ensures the measurement accuracy;
    5) Unique sample fixture design, suitable for various specifications of thin film batteries, easy to clamp, good electrode contact, low interference to weak signal test;
    6) Complete fully automated dedicated system software.
     Optical bias technology:
    For multi-junction batteries, when measuring one of the batteries, it is necessary to bias the other cells to make them fully conductive. Generally, it is necessary to select the bias light according to the range of the spectral response of the battery. In the band, in which band the battery responds, which band of light is selected to turn on the battery, so that the current generated by the measured battery can be smoothly output. The standard configuration only contains one bias light source. Users can choose two bias light sources as needed. Each bias light source can work independently. For solar cells with three or more junctions, the offset method can be used to measure and solve the problem. Filters in certain bands are difficult to match, which is a relatively unique design in solar test systems currently on the market.
