摘要

目前染料敏化太陽能電池(DSSC)之製程中最費時的為塗佈TiO2(至少兩次，為獲得較佳效率，通常塗佈五次)以及吸收染料敏化劑(至少8小時，為獲得較佳效率通常採用24小時)。本研究以靜電紡絲製備電池之光陽極(TiO2電極)以取代習知的製程，不但產出的電池效率與習知相當，而且可以簡化製程、大幅縮短生產時間並提高良率。以靜電紡絲連續製程來製造染料敏化太陽能電池(DSSC)不但降低製作成本，進而大幅提升染料敏化太陽能電池(DSSC)的競爭力，並促使商品化時程加速，還可增加靜電紡絲之附加價值，並提昇其應用領域；進而提昇傳統紡織產業的市場競爭力。

Generally, the efficiency of the electron-injection process is strongly dependent on the bonding structure of the dye molecules absorbed on the TiO2 film. In addition, electron transfer in the DSSC is strongly affected by the electrostatic and chemical interactions between the TiO2 surface and the absorbed dye molecules. The TiO2 film usually need to coat more than twice. In order to let dye molecules suffieiently absorbed on the TiO2 film, it usually immerse the film into the dye solution more than 8 hours. We have successfully demonstrated that the electrospun photoanode could provide a competitive alternative to the fabrication of DSSCs with less time and lower cost. We believe the simple and cheap merits of electrospinning will increase its potential in DSSCs and help them move to commercialisation quickly. The overall conversion efficiency of DSSC with photoanode prepared by the electrospun process showed slightly lower than that of conventional process.
