A light detecting array structure and a light detecting module are provided. The light detecting array structure includes a plurality of first electrodes, a plurality of second electrodes, a first carrier selective layer, a second carrier selective layer, and a light-absorbing active layer. The second electrodes are disposed on one side of the first electrodes. Between the first electrodes and the second electrodes, a first carrier selective layer, a light-absorbing active layer and a second carrier selective layer are disposed. The light detecting module includes the light detecting array structure and a control unit. The control unit is coupled to the first electrodes and second electrodes, selectively provides at least two cross voltages between each of the first electrodes and each of the second electrodes, and reads photocurrents flowing through the first electrodes and second electrodes.
