• work, a new type of self-powered, high-performance ultra-thin p-Si/n-ZnO nanowire (NW) flexible photodetector (PD) and its application as full-spectrum optical sensor and pyroelectric nanogenerator (PENG) are demonstrated. The working mechanism of PDs for PENGs is carefully investigated and

• device can realize full-spectrum optical communication. An experiment in which the PENG powers other devices is designed to further demonstrate the proposed working mechanism. This work provides an effective approach to realize self-powered, high-performance PDs for full-spectrum communication. Also, the

• fabrication of the PENG utilizing a simple and low-cost method shows its potential applications in self-powered flexible electronic devices.

• measured as a function of time in the dark and under illumination. For illumination, the full spectrum of the Xe-lamp was used. The transient photocurrent curve recorded during the first cycle of the illumination is shown in Figure 4a. The bias was applied at time 0, which caused a current jump from 0 to
