Abstract Optoelectronic logic gates (OELGs) are considered a promising alternative to traditional electronic gates, thanks their high computational speed and low power consumption. Meanwhile, there enormous challenges including complex structures single‐function. In this study, the optoelectronic gate device is prepared merely through single Cs 3 Bi 2 Br 9 photodetector. The bidirectional photoresponsive behavior of exhibited under bias voltages modulated by change current level. five fundamental OELGs (AND, OR, NOR, NOT, NAND) demonstrated successfully applying voltage ±1 mV. Moreover, can be adjusting voltage. To create multifunctional array platform, 5 × constructed with 100% accuracy for basic OELGs. For practical applications, these arrays demonstrate great potential in imaging image processing.
