| titleOfInvention | System and method for rapidly testing external quantum efficiency of solar cell based on frequency division multiplexing |
| abstract | The invention discloses a system and a method for rapidly testing external quantum efficiency of a solar cell based on frequency division multiplexing, and relates to the technical field of solar cell testing devices and methods. The system comprises a light source, a filter wheel, a slit, a dispersion unit, a spatial light modulation unit, a mixing and focusing optical device, a standard silicon detector, signal acquisition equipment and a PC (personal computer). The light source emits white light, the white light is filtered by the filter wheel and dispersed by the dispersion unit to form a plurality of dispersion light beams with different wavelengths, then the dispersion light beams irradiate on the space modulation unit to be modulated based on a frequency division multiplexing method, finally the dispersion modulation light is polymerized back to a multi-color light beam to irradiate on a sample to be detected, and the acquired photocurrent signal is subjected to inverse Fourier transform demodulation processing to obtain the spectral response of the battery. Compared with the traditional monochromatic measurement system method, the method greatly improves the detection speed, and has the characteristics of high signal-to-noise ratio, rapidness, accuracy, economy, high efficiency, stability and high repeatability. |
