CsPbIxBr1-x thin film with spontaneous polarization can be made into the self-powered photodetector based on light induced pyroelectric effect. It can perform without an external power source to meet the demands of the portable and wearable nanodevices. Here, a novel self-powered photodetector based on all-inorganic halide perovskites CsPbIxBr1-x thin film is fabricated, which shows an ultrafast response speed of less than 6μs under the laser illumination at zero bias. Also, the response characteristics of the self-powered photodetector from UV to near infrared are experimented and exhibited. Especially, the device has a higher response to 405nm UV light than other. This work extends the potential applications of perovskites in energy scavenging and self-powered sensor systems.
