Pyro-phototronic effect: An effective route toward self-powered photodetection

The Photodetector (PD) refers to an energy harvesting device that can directly convert light energy into electric current. Such a device has been widely used in different applications ranging from optoelectronics, and biomedical, surveillance to environmental monitoring. It consists of a heterojunction made up of various ceramic and hybrid materials. Especially, Self-powered PDs have attracted tremendous attention due to their significance in fundamental science, day-to-day life, and commercial value. Importantly, self-powered devices can reduce the dependency on an external power supply, making them self-sustainable for powering smart devices. Moreover, the pyro-phototronic effect (PPE) in self-powered PDs that boosts device performance beyond expectations is appealing thanks to the modulation of photo-generated charge carrier separations, transportation, and extraction.
