In this report, we suggest diverse concept to integrate carbons as an essential factor of dye-sensitized solar cells (DSSCs). First, we demonstrate block copolymer (BCP) mediated synthetic protocols for hybrid carbon/TiO2 beads. By distributing the carbon species into TiO2 photoanode, the efficiency of DSSC cell was improved by 10% compared with that of TiO2 based DSSCs. Next, we present a fabrication route for hybrid Pt/carbon counter electrodes (CEs) with an extremely low loading of Pt derived from BCP templates. DSSCs employing hybrid Pt/carbon CEs exhibited similar conversion efficiencies compared with conventional cells based on sputtered Pt thin films. Finally, we introduce a new concept to incorporate carbon species obtained from glucose. It led to higher photovoltaic performances than DSSCs employing neat TiO2 photoanode, especially providing a better strategy than conventional methods using graphene or carbon nanotube in terms of convenience for use and ease to be integrated. |
