| dc.description.abstract | Physical inductance as an origin of inductive-loop (or negative cap) in perovskite solar cell is proposed. Light/bias induced inductive loop, abnormal transient response and inverted hysteresis were put together as consequence of light/bias induced inductance. Non uniform current density due to ion channel is suggested as an origin of inductance, and presence of ion channel in inverted hysteresis device were shown by HRTEM and EDS. | - |
| dc.description.abstract | 페로브스카이트 태양전지의 인덕티브 루프(혹은 음의 축전기 성분) 의 원인으로써 실제 인덕턴스를 제안하였다. 광/전압에 의한 인덕티브 루프, 이상과도현상 그리고 역전된 히스테리시스가 모두 광/전압에 의한 인덕턴스에 의한 것임을 주장하였다. 인덕턴스성분이 이온 채널에 의한 비균일 전류밀도 에 의한 것임을 제안하였으며, HRTEM 측정과 EDS 측정을 통해 역전된 히스테리시스를 보이는 소자에서 이온 채널이 존재함을 보였다. | - |
