The Influence of Sintering Temperature on the Performance of Dye-Sensitized Solar Cell

Abstract:

This study investigated the effect of the sintering temperature on the performance of a dye-sensitized solar cell (DSSC). A nanocrystalline TiO2 layer was fabricated on the ITO substrate using the doctor blade technique, and the working electrode was then sintered in a high-temperature furnace. The working electrode with a TiO2 thin film was immersed in the solution of the CuPc dye (copper phthalocyanine 32 16 8 C H CuN ) powder for 12 hours. Finally, the DSSC was assembled, and the short-circuit photocurrent and the open-circuit photovoltage of DSSC were measured using a home-made I-V measurement system. The short-circuit photocurrent significantly increases from 8.02 to 16.85 μA as the sintering temperature increases from 165 to 550 C  . Furthermore, the open-circuit photovoltage substantially increases from 0.084 to 0.42V as the sintering temperature increases from 165 to 550 C  .
