페로브스카이트 태양전지는 차세대 태양전지로써 몇 년 사이에 매우 큰 폭으로 효율이 증가하고 있으 며 활발한 연구가 진행되고 있다. 페로브스카이트의 태양전지의 구조는 전자전도체, 페로브스카이트 광 흡수체, 정공전도체, 전극으로 구성된다. 전자전도체는 전자 포집성이 우수한 다공성 TiO2 층과 TiO2 박 막 층으로 구성된다. 균일한 박막 TiO2 를 형성하는 것은 페로브스카이트 태양전지의 개방전압 특성에 기여한다. TiO2 박막을 제조하는 방법으로써 용액을 사용한 스핀 코팅 법은 간편하게 제조가 가능하나, 일정한 두께의 박막을 형성하지 못하고 균일하지 못하는 단점을 가진다. 본 연구에서는 RF 마그네트론 스퍼터를 이용하여 보다 균일한 TiO2 박막을 제조하였다. X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Light IV, Quantum Efficiency (QE)로 분석하였다. 이를 통하여 제조방법 차이에 따른 페로브스카이트 태양전지의 영향을 분석하였다.

SnS (tin monosulfide) thin films obtained by atomic

layer deposition (ALD)

Hu Weiguang, Young Joon Cho, and Hyo Sik Chang*

Graduate School of Energy Science & Technology, Chungnam National University, Daejeon, South Korea Tin monosulfide (SnS) is one promising candidate absorber material which replace the current technology based on cadmium telluride (CdTe) and copper indium gallium sulfide selenide (CIGS) for its suitable optical band gap, high absorption coefficient, earth-abundant, non-toxic and cost-effective. During past years work, thin film solar cells based on SnS films had been improved to 4.36% certified efficiency. In this study, Tin monosul fide was obtained by atomic layer deposition (ALD) using the reaction of Tetrakis (dimethylamino) tin (TDMASn, [(CH3)2N]4Sn) and hydrogen sulfide (H2S) at low temperatures (100 to 200 oC). The direct optical band gap and strong optical absorption of SnS films were observed throughout the Ultraviolet visible spectroscopy (UV VIS), and the properties of SnS films were analyzed by sanning Electron Microscope (SEM) and X-Ray Diffraction (XRD).
