The full solid-state, intrinsic cutoff solar-blind UV photodetectors are widely used in the military and civilian fields. Herein, to achieve real-time solar-blind UV signal detection for application in portable equipment, the material epitaxy, device fabrication, and performance characterization of high-performance back-illuminated AlGaN-based solar-blind UV photodetectors are conducted at first. Based on the photodetector, a discrete signal amplifier circuit is subsequently designed and prepared to fulfill the weak solar-blind signal detection. Through assembling the amplifier circuit with the AlGaN-based solar-blind UV photodetector, it can output real-time voltage signal with different amplitude according to the intensity of the incident UV light signal. This study is of great significance for developing a portable solar-blind UV detection system.
