Description
Summary:A dye anchored counter electrode (DACE) based dye sensitized solar cell (DSSC) is fabricated. The multi-dyed N719 and PCH001 DSSC with carbon nanohorns (CNHs) as the counter electrode revealed a broad spectra of the incident photon to current conversion efficiency (IPCE) and an efficiency ( η ) of 7.14%. The device with a FTO/TiO 2 front electrode without dye and the DACE (FTO/Pt/TiO 2 /N719) shows η = 1.38%. This work evidences that the transfer the photo-excited electrons in the DACE contributes in the photovoltaic conversion. DACE-DSSCs are an alternative potential architecture for multiple dye sensitized solar cells for enhanced performance. The counter electrode architecture of a DSSC is optimized. A DACE based DSSC with multiple dyes (PCH001, N719), and CNH produces broad IPCE spectra and a conversion efficiency ( η ) of 7.14%, revealing the promise of this architecture for multiple dyes sensitized solar cells.
