Recently, Breakthrough in the application of flexible transparent electrode and LED had been achieved by Nano Photoelectric Material Institute with NUST and later was published in subject top journals, Nano Letters (Impact Factor 12.9) and Angewandte Chemie International Edition (Impact Factor 11.3), with doctoral student Song Jizhong and Professor Zeng Haibo being the prime author and responding author respectively. Due to the highly assessment of subeditor, Professor Zeng has received the invitation of the editor of Angewandte Chemie International Edition to write the forefront overview with the topic, the latest research progress on new flexible transparent electrode in 2015.
Transparent electrode, an indispensible photoelectric functional material, plays an important role in numerous electronic and photoelectric equipments. However, it is now the key moment for either industry application or fundamental research of the transparent electrode to upgrade and update. On one hand, ITO, as the main transparent material in today’s market, has faced the serious challenges, like indium resources are gradually dying out; manufacturing process costs more than enough. On the other hand, the components and parts are transforming from rigid chips into soft, flexible and wearable ones, which undoubtedly requires more for transparent electrode. Hence, flexible transparent electrode made of nano-crystal ink has come into exist. The project firstly avoids rare metals indium, and moreover, it complies smoothly with various printing technology.
