Layer‐by‐layer self‐assembly is a versatile technique for the construction of well‐defined nanoarchitectures with outstanding electrical and photoelectric performances. The revelation of a potential charge‐transfer mechanism of extraordinary electrical and photoelectric behaviors is profound in the design of modern electrical and photoelectrical devices. With the aim of revealing the potential charge‐transfer mechanism in conducting multilayer films, in this study, we fabricated [poly(styrene sulfonate)/polyaniline] n [(PSS/PANi) n ] multilayers with peculiar electrical and photoelectrical features. The fantastic increments in sheet conductivity and photoelectric response were believed to be the percolation reflection of accumulative electrons tunneled across the insulating PSS from the bottom to the top of the conjugated structure of PANi. These profound phenomena, along with simple fabrication and a well‐defined architecture, promise that the conducting multilayers will be good candidates for electronic and optoelectronic nanodevices. © 2013 Wiley Periodicals, Inc.
