Abstract—As one method of making dye sensitized solar cell (DSSC), electrophoresis deposition (EPD) which laminates TiO₂ on anode using two electrodes is practical way. Because it linked with low-temperature firing in case of espousing plastic substrate. In addition to being able to cut cost of experimental devices. However it has been reported that cracks appear and get bigger on surface of TiO₂ layer depending TiO₂ thickness. In this paper, we conducted discontinuous electrophoresis and compared with continuous about surface condition of TiO₂ layer and conversion efficiency. We used a glass substrate coated FTO as an anode and pt-FTO as a cathode. We adopted MK-2 dye which was an organic pigment. As a result of experiment, we could realize improvement of TiO₂ surface condition and progress conversion efficiency in case of discontinuous (2.47%) than continuous (2.08%) under illumination with 100 mWcm-2 (AM 1.5) simulated sunlight. Moreover, we proved that it was better dividing number of times.
