Optoelectronic devices and interfaces therein have captured great attention in both scientific and industrial communities because of the wide variety of their unique properties. From a materials chemistry point of view, each layer and individual component of an optoelectronic device possesses the possibility of flexible chemical modification, making it feasible to dope, mix, and physically/chemically modify the interface. Exploiting the novel properties in optoelectronic devices with diverse layerings of metals, semiconductors, and insulators, along with the interfaces between them, leads to new electronic device designs, including functional transistors, biodetection devices, and flexible electronics, as well as other types of traditional optoelectronic devices, such as photodetectors, photovoltaic devices, and light‐emitting devices, with unprecedented characteristics or unique functionalities. This article reviews the recent developments and challenges and provides a perspective on the exploration of interface‐engineered organic optoelectronic devices for future applications in electronics and optoelectronics.
