【 摘 要 】

Dye-sensitized Solar Cell (DSSC) is a solar cell that has great potential in the future because of the cheaper cost of fabrication and environmentally friendly basic ingredients. This study aims to determine the effect of type of screen on the TiO2layer as the active electrode DSSC. The active electrode TiO2based DSSC fabricated by the method of double layer. Efficiency Dye-sensitized Solar Cell (DSSC) can be obtained from the current-voltage curve I-V meter. Nanofiber on the nanoparticles can reach a highest efficiency of DSSC about 0,015%. The second variation of between nanofiber-nanoparticle layering, and nanoparticle-nanofiber, it appears that the nanofiber layer of nanoparticles above, no significant changes, namely in 10 minutes η = 0.014965; 15 minutes η = 0.011021 and 20 minutes η = 0.013332. This is demonstrated by the nature of the dominant nanofiber as a photon trap covered by the nature of the dominant nanoparticles absorb the dye, so that overtime does not affect the incoming electron. While the results of nanofiber layer on the nanoparticles changed significantly in the variation of 20 minutes, ie η = 0.00283. You can also see the most optimum time was 15 minutes, which is η = 0.01559. This may be due in this 15 minute nanofiber coating has a thickness that is optimum so that electrons can reach the electrode diffuse due to the interaction between photons and the dye more.
