$Ag_2Se$ 전극을 제조하고 은이온에 대한 지시전극으로서의 성질을 조사하였다. Epoxy 수지를 Ag_2Se 전극의 binder로서, Silver paste를 감응막과 은판의 접착제로서 사용하였다. 감응막은 10ton/$cm^2$로 가압성형 한다음 질소분위기에서 200${\sim}$$500^{\circ}C$로 sintering한 후 전극을 제조한 결과sintering 하지않은 전극보다 감응성이 우수하고 견고하였다. 또한 $Ag_2Se$전극보다 감응성이 우수하였다. 은이온농도의 변화에 따르는 감응도는 10-6M까지 직선관계를 유지하였다. 대부분의 중금속 이온은 방해하지 않으나 수은(II) 이온이 크게 방해를 하였으며 음이온인 halide, cyanide, thiocyanate 이온의 방해는 더욱 심하였다. 반면 이전극은 halide 이온 정량시 전위차적정법으로 사용할 수 있음을 알았다.

In this study, a surface treatment method using accelerated Ar ions was experimented for exposing the carbon nanotubes (CNT) from the screen-printed CNT paste. After making a cathode electrode on the glass substrate, photo sensitive CNT paste was screen-printed, and then back-side was exposed by UV light. Then, the exposed CNT paste was selectively remained by development. After post-baking, the remained CNT paste was bombarded by accelerated Ar ions for removing some binders and exposing only CNTs. As results, the field emission characteristics were strongly depended on the accelerating energy, bombardment time, and the power of RF plasma ion source. When Ar ions accelerated with 100 eV energy from the 100 W RF plasma source are bombarded on the CNT paste surface for 10 min, the emission level and the uniformity were best.

Ag thick film has been used for electrode materials with the excellent conductivity. Ag electrode is used in screen-printed silicon solar cells as a electrode material. Compared to photolithography and buried-contact technology, screen-printing technology has the merit of fabricating low-priced cells and enormous cells in a few hours. Ag paste consists of Ag powders, vehicles and additives such as frits, metal powders (Pb, Bi, Zn). Frits accelerate the sintering of Ag powders and induce the connection between Ag electrode and Si wafer. Thermophysical properties of frits and reactions among Ag, frits and Si influence on cell performance. In this study, Ag pastes were fabricated with adding different kinds of frits. After Ag pastes were printed on silicon wafer by screen-printing technology, the cells were fired using a belt furnace. The cell parameters were measured by light I-V to determine the short-circuit current, open-circuit voltage, FF and cell efficiency. In order to study the relationship between the reactivity of Ag, frit, Si and the electrical properties of cells, the reaction of frits and Si wafer on was studied with thermal properties of frits. The interface structure between Ag electrode and Si wafer were also measured for understanding the reactivity of Ag, frit and Si wafer. The excessive reactivity of Ag, frit and Si wafer certainly degraded the electrical properties of cells. These preliminary studies suggest that reactions among Ag, frits and Si wafer should optimally be controlled for cell performances.

유리기저에 실크스크린 인쇄기법을 이용하여 투명전극형성용 유기점액인 ITO와 silver paste로써 투명전극 및 금속 전극을 형성하고 SiO 막을 입혀서 액정 매트릭스 표시기를 제작하였다. Rubbing technique로 액정분자를 유리기저에 평행으로 배열시키고, 액정의 동적산란현상을 이용하여 3:1 주소지정방식으로 한글, 알파벳, 숫자 등의 표시를 시도하였다. 제작된 6μm 두께의 표시기에 전압을 변화시키면서 그에 따른 응답파형을 관찰하였다.

X-ray lithography was employed to fabricate ITO-less high resolution sustain electrodes for plasma display panel (PDP). A polyimide film based X-ray mask and Xray sensitive Ag electrode paste were fabricated to check their effect on the patterning of Ag electrodes with less than 30 ${\mu}m$ in width. The X-ray lithographic method was found to be useful for the high resolution sustain electrode patterns due to the high penetration power and low scattering property of X-ray source.

EPDM을 결합재로 사용하고, HRP를 고정시켜 과산화수소 정량을 위한 탄소반죽전극을 제작하고, 바이오센서로서 실용화 가능성을 살펴보기 위하여 전기화학적 특성을 고찰하였다. 실험 농도 영역에서 신호의 Lineweaver-Burk 도시가 보여준 좋은 직선성은 촉매력이 효과적으로 발휘될 수 있도록 EPDM이 전극 물질 속에서 HRP를 잘 고정하고 있음을 보여 주었으며, 이는 EPDM이 전극물질 결합재로 활용될 수 있음을 말하는 것이다. 전극은 낮은 전극전위($0.0\sim-1.0$ V vs. Ag/AgCl)에서 작동하였으며, 이 때 얻어진 신호는 높은 감도와 재현성을 보여 주었다. 특히 건조된 고무의 기계적 안정성은 탄소반죽 전극 실용화의 난제였던 실리콘 오일 결합재의 대체가능성을 열어주었다.

Platinized counter electrode is common in most of the dye sensitized solar cell (DSSC) researches because of its high catalytic activity and corrosion stability against iodine in the electrolyte. Platinum (Pt) film coating on fluorine doped tin oxide (FTO) glass surface by using alcoholic solution of hexachloroplatinic acid ($H_2PtCl_6$), paste containing Pt precursors or sputtering are widely used techniques. This paper presents a novel application of Pt ink containing nanoparticles for making platinized counter electrode for DSSC. The characteristics of Pt films coated on FTO glass surface by different chemical methods were compared along with the performance parameters of the DSSCs made by using the films as counter electrodes. The samples coated with Pt inks were sintered at $300^{\circ}C$ for 30 minutes whereas Pt-film and Pt-paste were sintered at $400^{\circ}C$ for 30 minutes. The Pt ink diluted in n-hexane was found to a promising candidate for the preparation of platinized counter electrode. The ink may also be applicable for DSSC on flexible substrates after optimization its sintering temperature.
