Alkyl chain length dependence of the charge transfer, recombination and electron diffusion length on the photovoltaic performance in double donor-acceptor based organic dyes for DSSCs |
| 초록 |
Dye-sensitized solar cells (DSSCs) have attracted much attention of many research groups on account of their benefits, for instance, of low-cost fabrication process with decently high solar energy-to-conversion efficiencies compared to conventional p-n junction solar cells. The organic dyes with double electron acceptors have recently been reported to be very favorable for the DSSCs, compared to those with single electron acceptor, due to the more efficient electron extraction paths from electron donor and the higher molar extinction coefficients. However, the DSSCs using the organic dyes have yet been much less stable than the Ru-based dyes, due to the formation of unstable radicals under continuous light illumination and the dye desorption from the TiO2 nano-particle surfaces. |
