This study investigated the photovoltaic properties and microstructure of perovskite solar cells (PSCs) with an ITO/SnO2/perovskite/HTL/Au electrode configuration, developed with varying sintering temperatures (100~200°C). The goal was to use SnO2 ink as the electron transport layer (ETL) by low-temperature sintering. TGA-DTA analysis was conducted to determine the optimum sintering temperature..... More

Low Temperature Growth of One-Dimensional Al and Al<sub>2</sub>O<sub>3</sub> Nano/Micro-Structures Using Al and SnO<sub>2</sub> Powder Mixture
Al과 SnO2 혼합 분말을 사용한 일차원 Al과 Al2O3 나노/마이크로구조의 저온 성장

Korean J. Met. Mater. 2021;59(9):677-681.   Published online 2021 Aug 4
DOI: https://doi.org/10.3365/KJMM.2021.59.9.677

One-dimensional Al and Al2O3 nano/microstructures were fabricated via thermal oxidation of Al and SnO2 powder mixtures at temperatures below the melting point of Al (660 oC). Furthermore, the synthesis process was carried out in air at atmospheric pressure, which made the process very simple and easy. Sn metal particles with..... More

Preparation of Li-Doped Indium-Zinc Oxide Thin-Film Transistor at Relatively Low Temperature Using Inkjet Printing Technology
잉크젯 인쇄 기술을 이용하여 상대적으로 낮은 온도에서 리튬이 도핑 된 인듐-아연-산화물 트랜지스터의 제작
Woon-Seop Choi
Korean J. Met. Mater. 2021;59(5):314-320.   Published online 2021 Apr 6
DOI: https://doi.org/10.3365/KJMM.2021.59.5.314

Inkjet printing is a very attractive technology for printed electronics and a potential alternative to current high cost and multi-chemical lithography processes, for display and other applications in the electronics field. Inkjet technology can be employed to fabricate organic light emitting diodes (OLED), quantum dots displays, and thin-film transistors (TFTs)...... More

Korean J. Met. Mater. 2019;57(1):28-37.   Published online 2018 Dec 14
DOI: https://doi.org/10.3365/KJMM.2019.57.1.28

The hot crack resistance and mechanical properties of flux cored arc (FCA) welds were investigated with three kinds of welding consumables having different boron (B) and manganese (Mn) contents for high strength carbon steel. The hot crack resistance, measured from self-restraint testing, strongly depended on the amount of B in..... More
