With the development of optoelectronics and the continuous pursuit of flexible optoelectronic equipment, transparent conductive film (TCFS) has become the focus of research. It plays a vital role in modern optoelectronic devices such as smartphones, tablets, display screens, solar cells, etc. in life.
However, traditional transparent conductive oxides (TCOS) (such as oxidation tin (ITO), etc.), due to the limitation of its preparation process, there are problems such as insufficient flexibility and insufficient conductivity. Essence Therefore, the scientific research team has also begun to explore new alternative materials and preparation methods to solve these problems. Among the numerous new type of photoelectric film, zinc oxide transparent conductive membrane has received widespread attention due to excellent optical characteristics. At the same time, the excellent high transparency and conductivity are considered a dark horse in this field.
Zinc oxide is an important functional material, which has the characteristics of conductivity, light guidance, voltage, sound light, luminous, utensil sensing and chemical catalytic. Zinc oxide can be adjusted and controlled in a wide range, and the film generated under different conditions has different functions. In addition to meeting excellent conductive and transparent characteristics, the pillar doped zinc oxide transparent conductive film developed by the research team can accurately control the quality of growth and control the appearance. It can form a surface appearance with photon crystal characteristics to make it more efficient in optical extraction.
In addition, ITO still has an inherent problem: the materials used are scarce. In contrast, zinc oxide transparent conductive film does not exist. From the perspective of raw materials, zinc oxide uses zinc and oxygen, and the reserves of the two are much higher than the 铟 used by ITO. This makes zinc oxide transparent conductive film has rich raw materials, low cost, simple craftsmanship, easy to achieve doping, more environmentally friendly advantages, and has excellent stability. In addition to the high visible light penetration rate and excellent transparent conductive characteristics developed by the pillar doped zinc oxide transparent conductive film developed by the research team, they also have a low resistivity and strong thermal stability, and the nitrogen -vaphed LED LED The extraction efficiency of glowing is higher, and it has broad application prospects in the field of photovoltaic and photovoltaic devices.
