Dye-sensitized solar cell (DSC) consist of photo electrode, electrolyte and counter-electrode. Among these, role of counter-electrode is very important because catalyst on the counter electrode let electrons pass through it self from external circuit to tri-iodide in the redox electrolyte. Several materials have been applied to DSC as counter electrode catalyst so far. Also, carbon nonotube (CNT) is already well known as counter electrode catalyst. In this study, characteristic of DSSC affected by sintering temperature variation of CNT paste is studied. As a result, there was nearly no change of the characteristic of DSSC.
