Effect of Organically-Modified Titania Nanoparticles on the Performance of Poly(3-hexylthiophene): PCBM Bulk Heterojunction Solar Cells |
| 초록 |
In search of new materials suitable for the electron-transporting interlayers in PSCs, the surfaces of TiO2 nanoparticle (TiO2NP) are modified and introduced between the active layers and the electrodes in the present study. The surface-modified TiO2 nanoparticle (mTiO2NP) interlayer improves the organic-metal interface in the BHJ solar cells of P3HT:PCBM without the need for surfactants, and their film-to-air surfaces becomes smooth without any pinholes or other gaps. It plays a crucial role of an electron-harvesting layer of the BHJ solar cells of P3HT:PCBM and blocks holes the organic-metal interface. In addition, mTiO2NPs also play an additional role of diffractive layer to provide an efficient way of achieving light trapping in PSCs. The deposition of mTiO2NPs an interlayer is relatively simple and convenient, and can be processable through spin-coating. |
