Flexible Dye-sensitized Solar Cells by a Low-temperature Sintering Method

저온소결법에 의한 플렉시블 염료감응 태양전지

A new binder-free $TiO_{2}$ paste was prepared by common ion applying effect, enabling low temperature fabrication required for flexible solar cells. The binder-free and high viscosity $TiO_{2}$ coating solution was produced by adding 7.5% aniline in $TiO_{2}$ colloid solution obtained from the high pressure water-heat response method. The resulting pastes had high level of viscosities proper for optimal coating and thus revealed excellent performances in terms of thickness uniformity and I-V characteristics.
