초록
본 논문에서는 레이저 dewetting에 의해 형성된 은 나노입자들의 국소 표면플라즈몬 공명이 감응형 TiO 2 태양전지의 전류밀도및 효율 향상에 유용하게 이용될 수 있음을 보여준다. 전도성 유리기판 위에 증착된 은 박막을 펄스 레이저 조사에 의해 나노입 자로 변환시킨 후 이 기판을 사용하여 감응형 TiO 2 태양전지 셀을 제조한 결과, 은 나노입자를 포함하지 않은 대조군 셀에 비해 성능이 보다 향상됨을 확인하였다. 이는 은 나노입자들에 의한 국소 표면플라즈몬 공명 현상으로 인해 가시광 영역에서의 광수확이 증대되었기 때문으로 분석된다.
Abstract
In this paper we show that the localized surface-plasmon resonance of Ag nanoparticles produced by laser dewetting can be effectively utilized for improving the photocurrent and efficiency of a dye-sensitized TiO 2 solar cell. An Ag thin film deposited on a conducting glass substrate was dewetted into nanoparticles by a pulsed laser. A dye-sensitized TiO 2 solar cell fabricated on this substrate containing the Ag nanoparticles exhibited improved photovoltaic performance, compared to a reference cell. This is attributed to the increased light trapping that arises from the localized surface-plasmon resonance of the dewetted Ag nanoparticles.
