Photoelectric detection array, photoelectric detector and laser radar

The embodiment of the invention provides a photoelectric detection array, a photoelectric detector and a laser radar. The photoelectric detection array comprises a transparent substrate; the transparent common electrode is positioned on the first surface of the transparent substrate; the absorption layer is positioned on the second surface of the transparent substrate and is used for absorbing light energy of light to be detected, which is incident through the common electrode and the transparent substrate, and generating light current based on the absorbed light energy; the second surface is an opposite surface of the first surface; the plurality of independent electrodes are distributed in an array mode, and the plurality of independent electrodes and the common electrode are distributed on different sides of the absorption layer; and each independent electrode is coupled with the common electrode and is used for outputting voltage corresponding to the light current generated by the absorption layer at the
