Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a photovoltaic type organic infrared semiconductor detector. Background technique [0002] Infrared light is an electromagnetic wave that cannot be directly observed by the human eye and has a wavelength greater than 760nm, which is between visible light and microwaves. To convert this infrared light into a detectable physical quantity, the usual practice is to convert it into a quantitative electrical signal. An infrared detector is a device that converts an invisible incident infrared radiation signal into a detectable electrical signal output. [0003] Infrared detectors are divided into photoconductive detectors and photovoltaic detectors according to their working principles. Among them, photovoltaic detectors are devices made by utilizing the photovoltaic effect. Compared with photoconductive detectors, photovoltaic detectors have the advantages of fast response,...
