Abstract
This chapter focuses on the evolution of Self-powered Photodetectors, from
single nanobelt to highly sophisticated Pyro-phototronic effect-assisted devices. The
essentials of the self-powered photodetector, from material characterization to device
engineering mechanism, are discussed in detail, such as Pyro-phototronic enriched
devices. This study provides a state-of-the-art research trend of the Pyro-phototronic
enriched self-powered photodetectors. Finally, a summary of various device structures
with their figures of merit and conclusions, along with the research gap, is presented.
This review focuses on providing valuable insights into improving self-powered
photodetectors.
