1 Introduction Optoelectronic devices act as foundational technologies in key areas such as communication, sensing, imaging, and artificial intelligence [1-4], where breakthroughs in device performance are critical for advancing industrial applications. For decades, research on photoconductivity has primarily focused on positive photoconductivity (PPC)—a mechanism where light exposure generates electron-hole pairs, boosting both carrier concentration and electrical conductivity (Scheme 1).
