The effect of dye coloring temperature on the dye-sensitized solar cells

A serious problem of the 21st century is the supply of energy resources. Reserves of fossil fuels are facing depletion: renewable energy resources must be developed in this era. Dye sensitized solar cells(DSC) have been very economical and easy method to convert solar energy to electricity. DSC can reach low costs in future outdoor power applications. However, to commercialize the DSC, there are still many shortages to overcome. When the DSC is commercialized in the near future, the productivity is an important factor. In the process of soaking in a dye, it usually takes 12${\sim}$24 hours. In this study, we varied the dye coloring temperature from 0$^{\circ}C$ to 60$^{\circ}C$. At the temperature of 40$^{\circ}C$, DSC cell showed the best performance. We also conducted the time variant experiment to reduce the manufacturing time. Counter electrode surface of DSC is deposited by RF magnetron sputtering under the conditions of Ar $2.8{\times}10^{-3}torr$, RF power of 120W and substrate temperature of 100$^{\circ}C$.
