Abstract

The self-powered photodetectors (PDs), characterized by their simple structure, low energy consumption and portability, are well-suited for meeting the needs of intelligent, wearable, mobile and portable electronic devices, showing promising potential in optoelectronics. A higher built-in electric field in the heterojunction is an advantageous condition for the excellent performance of self-powered PDs. Apart from choosing suitable materials to construct higher built-in electric field, utilization of the pyro-phototronic effect of materials can greatly tune up the built-in electric field. Additionally, the ferro-pyro-phototronic effect and the pyro-piezo-phototronic effect can further improve the performance of the self-powered PDs. Perovskite materials, as a star optoelectronic material, are widely used in self-powered PDs. In this review, we explore advancements in perovskite-based PDs, driven by the pyro-phototronic effect, aiming to offer novel insights and spur innovation in the realm of high-performance self-powered optoelectronics.
