1results about How to "Good photodetection performance" patented technology

The application provides a visible light positioning system and a preparation method of a silicon-based flexible photoelectric detector, and relates to the technical field of visible light positioning. The visible light positioning system comprises a fixed module with a curved surface structure, at least two silicon-based flexible photoelectric detectors, a data processing module and a positioning analysis module. The silicon-based flexible photoelectric detector comprises, from top to bottom, a front grid electrode layer, a hole transport layer, a passivation layer, an N-type monocrystalline silicon layer and a back metal electrode layer arranged in a stacked manner. The N-type monocrystalline silicon layer has a pyramid structure on both sides, and the hole transport layer, the passivation layer and the back metal electrode layer are conformally arranged with the N-type monocrystalline silicon layer. The silicon-based flexible photoelectric detector has the characteristics of flexibility, self-supporting and self-power supply, and has excellent photoelectric detection capability. The visible light positioning system has a simple structure, reduces the volume and cost, and realizes accurate positioning of the measured light source.
