A photoelectric conversion module converts light into electrical signals using a photodiode or APD, amplifying the current into a voltage. It is essential in optical communication, laser detection, and photometry. A photoelectric conversion module according to the present disclosure comprises: a substrate 1; a photoelectric conversion element 2; and a first sealing member 7, wherein the photoelectric conversion element 2 is sealed by the substrate 1 and the first sealing member 7, the first sealing member 7. A photoelectric conversion module includes a circuit board, a flexible substrate configured on the circuit board, with a concave structure having a first optical micro-reflection surface and a second optical micro-reflection surface formed opposite to the first optical micro-reflection surface, an. The purpose of the present invention is to provide a photoelectric conversion module that has a bypass diode function and that will not lose flexibility. These modules bridge the gap between raw optical signals generated by photoelectric sensors and the digital or analog inputs required by programmable logic controllers (PLCs) or distributed. This is where the photoelectric sensor conversion module plays a critical role.
