Abstract

The invention provides a characteristic testing device of an organic photoelectric sensor, comprising: a fixture main body, a PCB circuit board, an adjustable LED light source, a controller base, and a cassette; The buckle can completely fix the sample, and at this time, multiple spring probes correspond to multiple electrodes of the sample; PCB circuit boards can use different combinations of spring probes and positioning frames to test samples using a variety of masks; The three-dimensional translation stage can move the sample in the horizontal direction, so that the LED light source can illuminate multiple devices on the sample and obtain the performance parameters of multiple devices; the universal joint and focusing lens can change the angle, intensity and spot size of the light source; control The device integrates all the wiring required for testing, and the wiring is connected to the test fixture through specific holes, which can effectively prevent light leakage when using the dark box.

Description

technical field [0001] The invention relates to the field of photoelectric testing devices, in particular to a characteristic testing device of an organic photoelectric sensor. Background technique [0002] During the research and process development of organic photoelectric sensors, it is necessary to test the performance of organic photoelectric sensors. Generally, according to the photocurrent, dark current, spot unit power, and I-V characteristic curve (volt-ampere characteristic curve) of the organic photoelectric sensor, the relevant performance parameters such as the on-off ratio, external quantum efficiency, responsivity, and specific detectivity of the organic photoelectric sensor can be obtained. In the process of obtaining the photocurrent, dark current and I-V characteristic curves of organic photosensors, it is necessary to use a test fixture to position the organic photosensor under the adjustable LED light source. [0003] Existing organic photoelectric senso...
