Carbon nanotubes are one of the materials that can replace platinum as DSSC’s counter electrode. By utilizing carbon nanotubes (CNT), which is an organic material in place of platinum it is possible to create an inexpensive solar cell. However, there are still many problems with CNT such as low conversion compared with platinum and fast degradation in CNT. At the present time, it is to be large surface area when we fabricate CNT electrode sintered at 500°C with Electrophoretic Deposition (EPD). We measured how conversion efficiency changed by changing sintering temperatures. As a result, when CNT electrode sintered at 500°C, conversion efficiency was the highest and it was 2.46%.

This study investigates the applicability of a counter electrode with aP-type semiconductor oxide (such as NiO) on a dye-sensitized solar cell (DSSC). The counter electrode is fabricated by depositing an NiO film on top of a Pt film, which has been deposited on a Fluorine-doped tin oxide (FTO) glass using an ion-sputtering coater (or E-beam evaporator), using a simple spin coating method. This study also examines the effect of the average thickness ofTiO2film deposited on a working electrode upon the power conversion efficiency of a DSSC. This study shows that the power conversion efficiency of a DSSC with a Pt(E)/NiO counter electrode (4.28%) substantially exceeds that of a conventional DSSC with a Pt(E) counter electrode (3.16%) on which a Pt film was deposited using an E-beam evaporator. This result is attributed to the fact that the NiO film coated on the Pt(E) counter electrode improves the electrocatalytic activity of the counter electrode.

Dye Sensitized Solar Cell (DSSC) is more inexpensive and ecofriendly than silicone solar cell from structure. It has been reported that DSSC made by used ruthenium reaches 10.7 % [1]. However there are some contradiction so that a pigment named Ruthenium complex which is toxic is used in it. So we investigated to solve these problems using MK-II dye that is inexpensive and harmless. At the same time, we explored what kind of influence in conversion efficiency from difference of coating thickness by Electrophoretic Deposition (EPD) method. This method can lead to use flexible materials [2]. Because letting to deposit Titanium oxide (TiO2), we can lower sintering temperature or less to plastic melting point. The result was cell’s conversion efficiency better than others in case of 90sec and 100sec of electrophoresis time. From our experiments it is able to be said that coating thickness made by 90sec and 100sec are suitable, and its difference affect conversion efficiency.
