碩士 === 國立臺北科技大學 === 有機高分子研究所 === 101 === The focus of this thesis is twofold. The first part of thesis focused on the effect of rare earth metal (REM) on the performance of dye-sensitized solar cell (DSSC). We successfully fabricated the REM photoanodes by lanthanum nitrate solution. The photoelectric efficiency of modified DSSC device can be enhanced up to 11 %. The set-up of DSSC effect analysis was applied to the recycled REM from recycling fluorescent powders. In the second part, we extracted lanthanum by acid treatment from the recycling fluorescent powders followed by dissolving the lanthanum powder in isopropanol to prepare the dip-coating solution for DSSC anode modification. The best photoelectric effect is up to 8.069 % which showed enhancement of 16.6 % compared to DSSC without REM modification.
