Research Summary
Energy Recognition
The main research is focused on light-harvesting, energy transfer and recognition for an applications of an energy harvesting and storage (organic solar cells and supercapacitor), as well as phosphorescent bioapplications such as bioimaging and photodynamic therapy. For those aims, we design and synthesize new energy donor and/or acceptor materials to enhance the efficiency of bulk hetero-junction solar cells and dye-sensitized solar cells using energy transfer. For real commercialization of organic solar cells, we are also interested in the fabrication of new device concepts and large area device by spray coating technology employing our developed materials. We also design and synthesize new phosphorescent biosensors for organelle and proteins and photodynamic therapy reagent for various diseases, such as cancer and Alzheimer. Furthermore our research interests are expanded into fuel cells, water splitting, dye-sensitized solar battery and/or supercapacitor, organic light-emitting diodes (OLED), light-emitting electrochemical cells (LEC).

본 연구실의 테마는 빛을 활용하여, 즉 빛을 모으고 이를 인식하고 전달하는 현상을 이용하여 에너지를 모으로 저장하는 연구 (유기태양전지, 슈퍼커페시터) 인광 바이오 이미징 및 광치료에 관한 연구를 진행한다. 본 연구를 위해 새로운 에너지 주개와 받개 물질을 합성하여 유기태양전지 및 염료감응형 태양전지의 효율을 높이기 위한 에너지 전이에 관한 연구를 진행한다. 태양전지를 실생활에 상용화 시키기 위해 새로운 소자를 디자인하고 제작하는 연구를 초음파 스프레이를 기반으로 진행한다. 본 연구실은 또한 단백질 및 세포 소기관을 인식하기 위한 인광 바이오 센서 및 알츠하이머 및 암등에 사용되는 광치료제에 관한 연구도 진행한다. 나아가 이러한 빛 에너지 활용 기술을 기반으로, 연료전지, 물분해, 염료 감응형 밧데리 및 슈퍼 커페시터, OLED, LEC, 등으로 보다 다양한 연구를 진행하고 있다.
