摘要：
Single-layer hollow ZnO hemispherical arrays behaving light trapping effect as the electron transport layer in perovskite photodetectors were first introduced.Our photodetectors showed high self-powered performances with a LDR of 120.3 dB, a detectivity of 4.2 × 1012 Jones, rise/fall time of 13/28 µs and the f−3 dB of up to 28 kHz.Benefiting from the high device performance, the photodetector was demonstrated to the directional transmission of encrypted files as the signal receiving port with super high accuracy.
