Problems solved by technology

[0006] ① The photoelectric device is exposed to the air during measurement. When the photoelectric device is sensitive to moisture and oxygen, the repeatability of the performance test of the photoelectric device is not good. If it is tested in a glove box or after packaging, the operation steps are complicated and the cost is high;
[0007] ②Because the electrodes of photoelectric devices are generally thin, and the electrodes of photoelectric devices need to be clamped manually with clips during testing, the electrodes are often damaged due to improper manual operation, and accurate test results cannot be obtained;
[0008] ③ During the test, manual operation is required, point by point measurement, complex operation and low efficiency

Description

technical field [0001] The invention relates to an in-situ multifunctional photoelectric device probe testing device. Background technique [0002] At present, a variety of optoelectronic devices are widely used in people's daily life, and the research and development of each optoelectronic device requires repeated testing of its performance, so as to optimize its structure and evaluate its performance stability. The traditional test method in the laboratory is to place the photoelectric device in a glove box or in the air and measure it point by point manually. Taking the test of organic light-emitting diode (OLED) as an example, three sets of parameters are generally measured: the current-voltage curve of the light-emitting point, the brightness and spectrum. The test methods of organic light-emitting diodes in the laboratory include the following: [0003] Clamp the positive and negative poles of a light-emitting point of the organic light-emitting diode device with a c...
