Dye sensitized solar cell (DSSC) is a well-known photovoltaic device that is used for low power application. One of the main components for DSSC is semiconductor material photoanode which will provide the pathway for electron transportation and thus determine the energy conversion efficiency of the DSSC. The most commonly used material for the semiconductor photoanode is titanium dioxide (TiO2).TiO2is a semiconductor material with wide bandgap material that is existed in three crystalline phase; rutile, anatase and brookite. This paper emphasizes the best annealing temperature for commercialized TiO2, 98% anatase powder where the temperature varies from 300 oC – 600 oC. Through this research, the best annealing temperature for anatase TiO2photoanode is at 420 °C (0.094%) with the crystallite size of 18.76 nm and particle size of 19 nm that is favorable for the dye attached and thus enhances the energy conversion efficiency of the DSSC.

Nanoporous and macroporous structures were prepared by using self-assembled monolayer (SAM) onto ZnO thin films in order to investigate the efficiency of dye-sensitized solar cells (DSSCs) produced using these films. Using SAM on ZnO thin films, it is obtained successfully assembled large-area, highly ordered porous ZnO thin films. Varying nanoporous radius is observed between 20 and 50 nm sizes, while it is 500–800 nm for macroporous radius. The solar conversion efficiency of 2.75% and IPCE of 29% was obtained using ZnO nanoporous/N719 dye/I−/I3-electrolyte, while macroporous ZnO given solar conversion efficiency of 2.22% and IPCE of 18%.

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%.

In this study, we attempted to develop a low-cost dye-sensitized solar cell (DSC) by substituting a screen-printed carbon electrode for the conventional platinum counter electrode. Carbon electrodes were formed from mixtures of activated carbon, carbon nanofiber, carbon black, and a resin. The best carbon electrode conversion efficiency obtained was approximately 90% that of a platinum-based electrode.
