Improved energy conversion efficiency of dye-sensitized solar cells based on the freestanding TiO2 nanotube arrays with carbon materials and scattering layer |
| 초록 |
Dye-sensitized solar cells were fabricated with closed- or open-ended freestanding TiO2 nanotube arrays as photoelectrodes that were decorated with carbon materials and large TiO2 nanoparticles to enhance the energy conversion efficiency. The main role of carbon materials is to improve the electron transports by pi-pi conjugation and the main role of large TiO2 nanoparticles is to improve the light harvest by scattering in the TiO2 nanotube arrays. The energy conversion efficiency of DSSC based on open-ended freestanding TiO2 nanotube arrays is increased from 4.47% to 5.39% compared to the DSSC based on closed-ended freestanding TiO2 nanotube arrays. In DSSCs based on the open-ended freestanding TiO2 nanotube arrays, the energy conversion efficiency of DSSC with carbon materials or scattering layer is increased from 5.39% to 6.19% or from 5.39% to 6.24% compared to the DSSC without carbon materials and scattering. Moreover, the energy conversion efficiency of DSSC based on the open-ended freestanding TiO2 nanotube arrays with carbon materials and scattering layer is increased from 5.39% to 6.98%, an enhancement of 29.50%. |
