Silicon PIN neutron detectors play an important role in nuclear science with advantages such as small size, light weight, low cost, and mature manufacturing process. This paper proposes a self-powered neutron detection system based on a triboelectric nanogenerator (TENG) and silicon PIN diode for the first time. The proposed environmentally efficient and low-cost TENG is connected to the detector through a rectifier bridge circuit. When the TENG powered silicon neutron detector is irradiated, the PIN diode generates defects in the silicon body, which leads to a decrease in the lifetime of excess carriers. The neutron dose can be measured by monitoring the change of the terminal voltage of the PIN diode.

硅PIN中子探测器具有体积小、重量轻、成本低、制造工艺成熟等优点，在核科学中发挥着重要作用。本文首次提出了一种基于摩擦纳米发电机（TENG）和硅PIN二极管的自供电中子探测系统。所提出的环保且低成本的 TENG 通过整流桥电路连接到探测器。当 TENG 供电的硅中子探测器受到辐照时，PIN 二极管会在硅体中产生缺陷，从而导致过剩载流子的寿命缩短。中子剂量可以通过监测PIN二极管端电压的变化来测量。
