技术领域technical field
本发明涉及光电子技术领域,具体涉及一种光电子器件的封装结构及封装方法。The invention relates to the field of optoelectronic technology, in particular to a packaging structure and a packaging method of an optoelectronic device.
背景技术Background technique
近10年来,随着光电子技术的迅速发展,发光二极管、有机发光二极管、太阳能电池、薄膜晶体管等光电子产品已逐步发展成熟,极大的改善了人们的生活,成为最具前景的高科技产业。同时,光电子信息技术在社会生活各个领域的广泛应用,也创造了日益增长的巨大市场,光电子信息领域的竞争正在世界范围展开,必将成为未来电子信息领域最为活跃的研究方向。In the past 10 years, with the rapid development of optoelectronic technology, optoelectronic products such as light-emitting diodes, organic light-emitting diodes, solar cells, and thin-film transistors have gradually matured, greatly improving people's lives, and becoming the most promising high-tech industry. At the same time, the wide application of optoelectronic information technology in various fields of social life has also created a huge growing market. The competition in the field of optoelectronic information is unfolding worldwide, and it will surely become the most active research direction in the field of electronic information in the future.
光电子器件主要包括有机电致发光器件、无机发光二极管、有机太阳能电池、无机太阳能电池、有机薄膜晶体管、无机薄膜晶体管、紫外光探测器、红外光探测器等,因其低碳环保的特性符合当下倡导的绿色生活主题而成为了最具发展潜力和应用市场的光电子器件。虽然有机光电子器件具有优良的性能,但仍然存在一些亟待解决的问题:由于其组成部分大都是采用有机材料制备在刚性(如玻璃或硅片)或柔性基板上,而有机材料本身对外界环境具有很强的敏感性,随着时间的推移,大气环境中的水和氧等成分会对材料产生严重的负面作用,从而未封装的器件在大气环境中放置后会使得器件性能逐渐降低,甚至完全失去性能。具体来说,氧气使有机材料产生氧化而会生成羰基化合物,此化合物是严重的淬灭剂,另外,材料变质就会形成黑斑,并伴随器件性能下降。水汽的影响更显而易见,它的主要破坏方式是导电电极对有机层化合物的水解作用,使稳定性大大下降。因此,对有机光电子器件进行封装,提高其使用寿命,抑制其性能的退化与失效,就显得十分必要,为而采用何种封装材料以及何种封装方法也就成了解决问题的另一个突破点。Optoelectronic devices mainly include organic electroluminescent devices, inorganic light-emitting diodes, organic solar cells, inorganic solar cells, organic thin film transistors, inorganic thin film transistors, ultraviolet light detectors, infrared light detectors, etc., because of their low-carbon and environmental protection characteristics in line with the current The theme of green life advocated has become the optoelectronic device with the most development potential and application market. Although organic optoelectronic devices have excellent performance, there are still some problems to be solved: since most of their components are made of organic materials on rigid (such as glass or silicon wafer) or flexible substrates, and the organic materials themselves are harmful to the external environment. Strong sensitivity, as time goes by, the components such as water and oxygen in the atmospheric environment will have a serious negative effect on the material, so that the performance of the unpackaged device will gradually decrease after being placed in the atmospheric environment, or even completely Lost performance. Specifically, oxygen oxidizes organic materials to generate carbonyl compounds, which are serious quenchers. In addition, black spots are formed when materials deteriorate, and device performance declines. The influence of water vapor is more obvious, and its main damage mode is the hydrolysis of the organic layer compound by the conductive electrode, which greatly reduces the stability. Therefore, it is very necessary to package organic optoelectronic devices, improve their service life, and suppress their performance degradation and failure. What kind of packaging materials and packaging methods are used for this has become another breakthrough point to solve the problem. .
