Lui Dezhang, Professor of the Department of Chemical Engineering, Department of Chemical Engineering, National Taiwan University of Science and Technology, Prof. Dian Dai of the Department of Chemical Engineering of National Taiwan University of Science and Technology, and Dr. Zhang Qiang and Wang Yuting, Ph.D., PhD students of the University of Science and Technology of Taiwan, and Michael Zharnikov, professor at the University of Heidelberg in Germany, co-published the report. This is the first time that the same electrode has been developed. The use of electrode buffer layer materials, innovative practices can be applied to solar cell power generation, light emitting diodes (OLED), will help promote the development of solar and mobile devices soft board.
According to Liao Dezhang, the electrode buffer layer is an organic photoelectric element and is a key structure of solar cells and light-emitting diodes. It can connect negative electrodes, positive electrodes and organic semiconductors. Buffer layer materials can improve the efficiency of organic photoelectric devices. In the past, scientists must look for two Different materials, the use of two different materials as an optoelectronic component of the cathode, anode buffer layer, not only increase the cost of the material, but also make the components in the manufacturing process is more complicated.
For the first time, Tektronix research team proposed the concept of innovation and developed a novel copolymerized polymer material. The same material can be used as a cathode and an anode buffer layer. This novel polymer material has been successfully applied to high-performance organic hybrid perovskite ( Perovskite) solar cells, organic polymer solar cells and organic light-emitting diodes (OLEDs), as component cathode, anode buffer layer. In addition to research results published in top international journals, it has also obtained patents from Taiwan and the United States.
Tektronix research team stated that anodes and cathodes are of different polarities. Generally, different layers of materials are needed to conduct the separate conduction. However, the team has developed innovative polymer materials that change the characteristics of materials with solvents to make them hydrophilic and hydrophobic. Two features, from hydrophobic surface conductive holes, hydrophilic surface conductive material. A single material can be used as an electrode buffer layer, will help simplify the process of solar cells, thereby reducing costs.
Taiwan University of Science and Technology's research results will help simplify the manufacturing process of solar cells and OLEDs, thereby reducing manufacturing costs and improving efficiency. For the future development of solar energy sources, smart phone, tablet, wearable devices and other OLED soft board development and application will produce Positive influence.
