ALD ZnO 버퍼층 증착 온도가 전착 Cu2O 박막 태양전지 소자 특성에 미치는 영향

허재영,트란 휴 만,허재영 한국태양광발전학회 2018 Current Photovoltaic Research Vol.6 No.1

Beside several advantages, the PV power generation as a clean energy source, is still below the supply level due to high power generation cost. Therefore, the interest in fabricating low-cost thin film solar cells is increasing continuously. Cu2O, a low cost photovoltaic material, has a wide direct band gap of ~2.1 eV has along with the high theoretical energy conversion efficiency of about 20%. On the other hand, it has other benefits such as earth-abundance, low cost, non-toxic, high carrier mobility (100 cm2/Vs). In spite of these various advantages, the efficiency of Cu2O based solar cells is still significantly lower than the theoretical limit as reported in several literatures. One of the reasons behind the low efficiency of Cu2O solar cells can be the formation of CuO layer due to atmospheric surface oxidation of Cu2O absorber layer. In this work, atomic layer deposition method was used to remove the CuO layer that formed on Cu2O surface. First, Cu2O absorber layer was deposited by electrodeposition. On top of it buffer (ZnO) and TCO (AZO) layers were deposited by atomic layer deposition and rf-magnetron sputtering respectively. We fabricated the cells with a change in the deposition temperature of buffer layer ranging between 80°C to 140°C. Finally, we compared the performance of fabricated solar cells, and studied the influence of buffer layer deposition temperature on Cu2O based solar cells by J-V and XPS measurements.

이차원밀도장에서의 유동을 해석하기 위한 수치모델의 개발

허재영 한국수자원학회 1993 한국수자원학회논문집 Vol.26 No.4

2차원 표층밀도분류의 내부흐름의 구조를 동역학적으로 구명하기 위해서는 수평방향의 운동방정식과 더불어, 근사되지 않은 완전한 연직방향 운동방정식에 의해 유체의 운동을 계산해야할 필요가 있다. 본 연구에서는 정수압근사를 도입하지 않은 기초방정식을 갖는 k-e 모델을 개발하여 정수압근사를 도입한 허재영등의 연구(1991)에서 얻어진 결과 및 중십(1984)의 실험결과와 비교하여 표층밀도분류의 전개과정에 있어서 연직방향 가속도 및 그 영향을 정량적으로 평가하였 To investigate the structure of internal flow hydrodynamically, the complete vertical equation of motion should be assembled into the model. In the present study a numerical simulation model not hydrodynamically approximated is established. From the compa

근현대 일본어로 쓰인 한국어 관련 문헌에 대한 사회언어학적 연구

허재영,권희주 한민족어문학회 2024 韓民族語文學 Vol.- No.104

이 연구는 메이지 이후 일제강점기까지 일본어로 쓰인 한국어 관련 문헌을 대상으로, 한국어 연구에 미친 일본어 논문과 저서들, 좀 더 넓은 의미로 보았을 때 일본어의 영향력을 살피고자 하는 목적을 갖고 있다. 지리, 역사적 관계로 인해 일본어로 쓰인 한국어 관련 자료는 메이지 이전에도 비교적 다수가 존재한다. 그러나 일본의 근대화 과정에서 조선에 대한 관심이 높아지면서, 일제강점기까지 한국어에 관한 연구가 적지 않게 산출되었다. 이러한 문헌이 산출된 데에는 일본 제국주의 팽창 과정에 따른 식민주의뿐만 아니라 서구의 근대 언어학 도입이라는 학문적 배경도 존재한다. 이 연구에서는 일본어로 된 한국어(조선어) 관련 단행본 134종, 논문 322편을 목록으로 작성하고, 문헌 유형 및 시대별 분포와 특징을 기술하는 데 중점을 두었다. 그 결과 1890년대부터 1920년대까지 다수의 단행본은 한국어(조선어) 학습과 관련된 것이며, 논문은 시대별로 비교적 고른 분포를 보이나 1930년대 이후 조선어 조사 활동 관련 문헌이 많아지는 것을 확인할 수 있었다. 한국어(조선어) 학습서의 분포는 일본 제국주의 식민지 언어정책, 조선어의 위상 등이 중요한 요인으로 작용하며, 한국어(조선어) 연구의 흐름에서는 역사-비교언어학적 연구 자료가 많은 비중을 차지함을 확인할 수 있는데, 이 또한 식민지 조선에서의 언어침식과 조선어의 위상 변화와 관련을 맺고 있다는 추론이 가능하다. This study focuses on Korean-related literature written in Japanese from the Meiji period to the Japanese colonial period. Its aim is to explore the impact of Japanese papers and books on Korean language studies and the broader influence of the Japanese language. Even before the Meiji era, there were already a significant number of Korean-related materials written in Japanese due to geographical and historical connections. However, with Japan’s increasing interest in Joseon during its modernization, a substantial amount of research on the Korean language was produced until the Japanese colonial period. This production of materials can be attributed not only to the colonialism resulting from Japanese imperialism expansion but also to the academic background of the introduction of modern Western linguistics. With this in mind, the study focuses on compiling a list of 134 books and 322 papers related to the Korean language in Japanese. It aims to describe the distribution and characteristics of the literature based on type and era. The findings reveal that from the 1890s to the 1920s, a large number of books were dedicated to learning the Joseon language. The papers, on the other hand, show a relatively even distribution across different periods. However, it was confirmed that the number of literature related to Joseon language research activities increased after the 1930s. The distribution of books for learning the Joseon language is influenced by Japanese imperialism’s colonial language policy and the status of the Joseon language. The study also highlights that historical- comparative linguistic research materials play a significant role in the flow of Joseon language research, particularly evident during the colonial Joseon period. It is possible to infer that there is a relationship between language erosion and changes in the status of the Joseon language.

Same Money, Different Names: Analysis of South Korean Aid to North Korea

허재영,박지연,Youngwan Kim 경남대학교 극동문제연구소 2017 ASIAN PERSPECTIVE Vol.41 No.4

In this study we suggest new approaches to conceptualizing South Korean aid to North Korea as equivalent to official development assistance (ODA) by looking at its historical background and present situation, as well as related laws. We review the characteristics and development of South Korean aid to North Korea, compare it to ODA, and suggest an innovative way of conceptualizing it as ODA. In particular, we assert that if South Korean aid to North Korea were considered ODA, South Korea would be able to effectively assist North Korea and become a more influential and responsible donor in international society.

행위자-네트워크이론의 적용: 주요 선거에서의 북한변수를 중심으로

허재영,김용호 경남대학교 극동문제연구소 2012 한국과 국제정치 Vol.28 No.4

The purpose of this study is to analyze how ahead of South Korean elections, issues concerning North Korea affect the outcome of elections, and further, utilizing a key concept of actor-network theory, ‘translation,’ determine the correlation between these two factors. In particular, this study focuses on the diversification of actors in the election process resulting from democratization and informationization. In major elections the influence of North Korean issues has changed since 1997, and furthermore, the effects of North Korean issues on the election results appear differently depending on the nature of the North Korean issues at hand. The results of the analysis into the background of this change effectuated through the steps of the translation process showed that factors such as distrust of the government, declining credibility of the media, people’s learning effect, and diversified media environment affected election results in combination.

대북 경제제재의 실효성 분석: 식량지원 중단을 중심으로

허재영,정진문 경남대학교 극동문제연구소 2016 한국과 국제정치 Vol.32 No.3

A decade has passed since North Korea's nuclear weapon program occurred which was because of its nuclear experiment in 2006. The international community has placed economic sanctions against North Korea which committed nuclear experiments for five times, through United Nations Security Council resolutions and individual countries have cut the economic support and trade. Especially, as food aid is withheld by the international community, it is assumed that North Korea is suffering from the food crisis. This article aims to look at the effects of food aid suspension as a tool of the economic sanctions in two stages; a stage where the international community imposed economic losses to North Korea and the other where North Korea changes its political strategy. Also, this paper finds reasons why North Korea does not yield possession of the nuclear weapons by analyzing the political pressure of North Korean civilians on its government, and the estimated cost-benefit between the countries who imposed sanctions against North Korea and North Korean leaders who are directly related to those countries.
