Development of thin film solar cell with high efficiency using the pure organic dye
- Professor Ryu-Dohyun team of chemistry , achieved world's highest energy conversion efficiency of 9.1%
- Improving an existing light photoactive layer thickness of 10 micrometers by 5 micrometers or less
- Development of solar PV systems possibly used indoor
□ Sungkyunkwan University (President Jeong-Gyusang) announced that chemistry professor Ryu-Dohyun research team in collaboration with Gwon-Taehyeok research team of Ulsan National Institute of Science and Technology synthesized new dyes and succeeded to reach world's highest efficiency of dye-sensitized thin film solar cell.
□ The study was selected as cover paper (Dissertation title: Photoactive Thin Films: Indoline-Based Molecular Engineering for Optimizing the Performance of Photoactive Thin Films) in materials sector of worldwide journal Advanced Functional Materials on Oct. 10th.
□ Mr. Ryu's team synthesized the new indoline dyes which are pure organic materials and applied those of the thickness of the photoactive layer is 2 micrometers (μm) or less to the thin film dye-sensitized solar cell achieving world-leading solar energy conversion efficiency of 9.1%. In addition to identifying the correlation of alkyl chain length and efficiency of organic dyes mechanism with a planar structure, it gave you a direction for future development of high-efficiency thin-film solar cells.
□ Dye-sensitized solar cell having transparency, flexibility and colorfulness has received the attention of many researchers because it is capable to operate in the interior and suitable for building integrated photovoltaic systems (BIPV). Therefore, thin film-like dye-sensitized solar cell of high efficiency development has been recognized as a very important part. However, organic dyes had been undesirable situation in terms of cost-effective energy conversion of thick film of more than 10 micrometers (μm).
□ Professor Ryu-Dohyun of SKKU who led the study said "The significance of this study is to develop a new organic dye-sensitized solar cell with high efficiency in thin film." He also said, "It presents a direction to the design of a new organic dye structure by identifying how the length of the alkyl chain attached to an organic dye having a plane structure affects the light energy conversion efficiency."
□ The study was carried out with the support of Ministry of Science, ICT and Future Planning and National Research Foundation of Korea.
