According to the detection method for rapidly detecting the defective silicon photomultiplier chip disclosed by the invention, the volt-ampere characteristic curve of the SiPM chip is measured by using the semiconductor precision parameter analyzer and the probe station, and the chip does not need to be sliced and packaged; whether the SiPM chip can work normally or not can be judged by directly observing whether the reverse volt-ampere characteristic curve of the SiPM chip has two concave inflection points or not through naked eyes, and if the reverse volt-ampere characteristic curve has no two concave inflection points, the SiPM chip can be judged as a defective product. According to the detection method provided by the invention, whether the reverse volt-ampere (I-V) characteristic curve of the SiPM chip has two concave inflection points or not can be judged through artificial intelligence image recognition, then whether the to-be-detected SiPM chip is a defective product or not is judged ...
