Through joint research, a team developed a 4-amino-TEMPO derivative with photocatalytic performance and successfully used it to produce high-performance and stable fiber like dye sensitized solar cells (FDSSCs) and fiber like organic light-emitting diodes (FOLEDs). This paper was published in the journal Materials and Energy Today.

The developed 4-amino-TEMPO derivatives have the characteristic of simultaneously improving the performance of fiber like dye sensitized solar cells (FDSSCs) and fiber like organic light-emitting diodes (FOLEDs).

Traditional materials are difficult to synthesize and produce on a large scale, and the reproducibility of devices using them is poor. The 4-amino-TEMPO derivative developed by the research team not only has a simple synthesis process and can be synthesized in large quantities, but also enhances the performance of FDSSCs and FOLEDs, improving the performance of these two electronic devices by more than 20%.

The research team, including Professor Chul Jin Ahn from Changyuan National University, as well as Dr. Jae Ho Kim and Dr. Myung kuan Song from the Energy and Electronic Materials Department of the Department of Surface and Nanomaterials, designed and synthesized a material with photocatalytic performance to improve the efficiency of FDSSC.

Synthetic materials exhibit high stability in both air and moisture, making them suitable for producing high-performance FDSSC and FOLED. In addition, it has been confirmed that it has excellent washing performance and resistance to mechanical impact.

4-Amino-TEMPO derivatives are applied in various electronic device fields, including solid electrolytes in lithium batteries, catalysts, solar cells, and organic light-emitting diodes. The uniqueness of this technology lies in its ability to produce on a large scale through simple processes, coupled with its cost-effectiveness. In addition, it provides versatility rather than a single function, making it widely applicable to various electronic applications.

These derivatives can be mass-produced at low cost, with less than 1 million Korean won per 100 grams. Utilizing this technology for local and large-scale production may bring unprecedented economic benefits to electronic equipment companies.

Dr. Song Mingkuan, the chief researcher of this study, said, "By utilizing multifunctional materials, we can improve the performance and reliability of electronic devices. We expect to apply them in different fields, including energy production and storage materials, as well as sensor materials."

The research team is continuing further research to use 4-amino-TEMPO derivatives for organic solar cells, perovskite solar cells, and organic light-emitting diodes, with the goal of mass production within a few years.
