Many research groups have studied tandem or multi-junction cells to overcome this low efficiency and degradation. In multi-junction cells, band-gap engineering of each absorb layer is needed to absorb the light at various wavelengths efficiently. Various absorption layers can be formed using multi-junctions, such as hydrogenated amorphous silicon carbide (a-SiC:H), amorphous silicon germanium (a-SiGe:H) and microcrystalline silicon (${\mu}c$-Si:H), etc. Among them, ${\mu}c$-Si:H is the bottom absorber material because it has a low band-gap and does not exhibit light-induced degradation like amorphous silicon. Nevertheless, ${\mu}c$-Si:H requires a much thicker material (>2 mm) to absorb sufficient light due to its smaller light absorption coefficient, highlighting the need for a high growth rate for productivity. ${\mu}c$-SiGe:H has a much higher absorption coefficient than ${\mu}c$-Si:H at the low energy wavelength, meaning that the thickness of the absorption layer can be decreased to less than half that of ${\mu}c$-Si:H. ${\mu}c$-SiGe:H films were prepared using 40 MHz very high frequency PECVD method at 1 Torr. SiH4 and GeH4 were used as a reactive gas and H2 was used as a dilution gas. In this study, the ${\mu}c$-SiGe:H layer for triple solar cells applications was performed to optimize the film properties.

이 논문에서는 시각적으로 명암이 인간의 정서에 영향을 미친다는 그레이브스의 명암이론을 적용하여 "라이온 킹" 에서 사용된 명암의 유형을 분석하고 작품 내에서 시각적으로 표현된 명암이 내러티브에서 전개되는 정서의 흐름과 어떠한 관계를 맺고 있는지에 대한 유형을 분석하였다. 이를 통하여 명암이 시각이미지에 끼치는 영향과 더불어 정서적인 분위기 표현에 중요한 요소로 작용한다는 점을 규명하고자 하였다. 애니메이션에서는 실사 영화와는 달리 내러티브상에서 전개되는 캐릭터들의 정서적 변화에 따른 이미지 연출이 더욱 강조 된다. 이는 관객들의 감정이입을 강화시키는 중요한 수단이 된다.

The purposes of this study are to comprehend the internal meaning and the external form in style of Greek statue's clothing in the light of linked solution, and to compare the characterizations of style of Greek statue's clothing with those in Greek Art. For these purpose, the theoretical studies about Greek art are preceded as a framework of this research, and then plastic characteristics of Greek statue's clothing and Greek art are analyzed by the documentary studies, For sources, photographs of Greek statue in Archaeological Museum and Louvre museum are used. The result is as follows. It is demonstrated that the characters of internal meaning in style of Greek art and Greek statue's clothing. The internal meaning of style of Greek art and Greek statue's clothing are as follows 1) Beauty of vital is subject that possessed life and movement and embodied dynamics or inherent power. 2) Beauty of moderation is subject that achieves some of its most impressive and practise a similar economy and restraint. 3) Beauty of character is subject that reveals the character of its wearer and has its own charm and distinction The Greeks clarified beauty by looking for mathematical proportions. It is the interrelation of part with one another, and with the whole, together with the additional element of good colour, which constitutes beauty as perceived by the eyes. The beauty in style of Greek statue's clothing consists of a sense of geometrical pattern, oder, symmetry, proportion, and rhythm.

Objectives : The meaning of the verses '久而增氣' and '氣增而久' from the 『Suwen·Zhizhenyaodalun』 were studied to complement previous annotations. Methods : Based on problems uncovered in previous annotations, the verses "久而增氣, 物化之常也" and "氣增而久, 夭之由也" were examined in detail. Results & Conclusions : Previous annotations on the verse "久而增氣, 物化之常也" have conflicting opinions. Therefore, related contents in the 『Huangdineijing』 were examined to resolve and complement existing interpretations. The meaning of '久' in the phrase "久而增氣, 物化之常也," not only has a temporal meaning but also refers to the Jing process[精化｣. The Jing process is where the Jing Qi is used to produce Jing through a feedback process that results in enlivening materials such as Jing, Qi, and Blood. The phrase "氣增而久, 夭之由也" refers to an early death caused by expansion of rough Qi that has failed to go through the Jing process because of excessive greed and failure to follow the seasonal principle. These phrases from the 『Suwen·Zhizhenyaodalun』 reminds us that the Qi's Jing process is an important factor in determining longevity, shedding new light on themes such as the pattern of food intake, cultivation, longevity, treating before illness, prevention, etc., for today.

A probe type fiber-optic sensing techique for electric current measurement is applied in this paper. The technique is based on the Faraday effect which meaning is that polarization state of light is rotated by magnetic field. In experiment, test wire is located at inside and outside of the probe to be measured. The experimental results prove not only linear property, but also polarization rotation property according to the distance from outside of probe.

The purpose of this study is to analyze the characteristics of the church architecture by Alvar Aalto. General features of Aalto's architecture are the result of accommodating Modern architecture with regional qualities of Finland. The church would be the best example for understanding his architecture because he designed most of his churches in the prime of life. He established architectural types in his 30s through Viipuri public library and Saynatsalo town hall. He developed these types and applied them to his whole design. His type acts as a principle of configuration of his church architecture rather than a copy of form and shows the characteristics in the field of building layout, dynamic space and the effective use of light. Therefore, Aalto's church architecture can be recognized as the representative of Modern Finnish architecture in that they developed the meaning of their specific context including site, region and cultural tradition without losing the concept and technology of Modern architecture.

One of the big difference between Aalto and other modem architects lies in an attitude that Aalto went beyond the principle of dogmatic functionalism. As an architect of Northern Europe, Aalto made unique architecture that showed both the language of modem architecture and vernacular architecture. He presented the best example which showed modernity in architecture without losing the meaning of the context including site, region and cultural tradition. With this background, Aalto developed his own typological design approach. As Wolfsburg church was designed in his prime of time, it showed the origin and evolutionary process of religious architecture as well as general features of Aalto's design. Clustered site plan, dynamic space of interior, the adequate control of natural light are representative characteristics found in Aalto's religious architecture. Wolfsburg church also demonstrate these features in more specific way including the continuity of wall and ceiling that showed spatial dynamics, free opening of wall which reflects on functions, and careful adjust of natural light. As a result, Aalto showed his typological design strategy that added new design ideas to the accumulated design vocabularies in the design of Wolfsburg church.

This thesis has purpose of explaining that blur color is not only appreciated but also undecided spacial color in contemporary space design and examining effects of space experience through the light. In keeping such developments, blur color has been perceived as the object of another tool in contemporary space and has provided us with new views by providing various program, sensor and screen from digital media. With the expansion of blur color, light has changed a spacial color structural that is not simple meaning factor into the essential concept. So this research aims to understand the principle of blur color in Olafur Eliasson's work, which of the fine artist in diverse fields from installation art to media art. The principle of blur color such as deconstruction of vanishing point, dimensional transfer, color gradation, and fiction of visual perception makes it possible to extract the expressed element and method of blur color. Meanwhile, the features of blur color such as sense of depth from viewpoint changes, hybrid from collapse of order, media metamorphosis from reconstitution and interaction from uncanny can be inferred from case analysis.
