Recent progress in functional two-dimensional photovoltaic photodetectors and related emerging applications

Abstract

The photovoltaic effect can directly harvest solar energy by converting optical signals into current without external bias and thus is a practical and sustainable approach for low-power, high-linearity, and gate-switchable optoelectronic devices. With the scientific modulation of carrier types, various photovoltaic heterostructures and related devices have been developed. Here, this article reviews the implementation of high-performance photovoltaic devices based on two-dimensional (2D) heterostructures of lateral and vertical structural configurations. And the related functional applications are mainly introduced further, including 2D polarization-sensitive-enhanced photovoltaic devices, 2D optoelectronic logic devices, and recent emerging 2D neuromorphic devices for artificial intelligence applications. For each section, the device design, performance, and working principles are systematically investigated and discussed. Finally, the challenges and perspectives of functional 2D photovoltaic detectors in relevant emerging applications are presented to accelerate future research.
