Abstract: Provided is a touch sensor type light-emission writing instrument such as a ball point pen or an automatic pencil, which includes an LED (Light-Emitting Diode) unit which is turned on or off by a touch sensor without special illumination at dark places or at night. The touch sensor type light-emission writing instrument includes an LED unit having two light-emission portions which are embedded in a leading-end opening portion of a body accommodating a pencil lead or a ball point internal chamber filled with viscous ink, and which emit light. The negative polarity of the LED unit is directly connected to a battery through a metal plate, a spring etc., in the writing instrument, and the positive polarity thereof is linked on an integrated-circuit (IC) board between the LED unit and the battery. The LED unit is turned on or off by detection of a touch sensor. Accordingly, in comparison with the conventional light-emission writing instrument employing the mechanical switching unit, the touch sensor type light-emission writing instrument employing the touch sensor type switching unit is simple in view of the structure, to thus decrease the number of trouble occurrence, and employs the LED unit having two light-emission portions, to thus provide good brightness so that shadow does not occur as well as to thus facilitate a switching operation of the LED unit, to offer a simply manipulative light-emission writing instrument.

Abstract: Provided are a dye-sensitized solar cell and a method for preparing the same. A dye-sensitized solar cell may include a photoelectrode comprising at least two kinds of dye layers having different wavelengths on a transparent conductive substrate, and a counter electrode comprising a platinum (Pt) layer on a transparent conductive substrate. The counter electrode may be arranged opposite to the photoelectrode and an electrolyte may be filled between the photoelectrode and the counter electrode.
