Synthesis and photovoltaic performance of a novel asymmetric dual-channel co-sensitizer for dye-sensitized solar cell beyond 10% efficiency

Role of Co‐Sensitizers in Dye‐Sensitized Solar Cells

“…Among the three co-sensitizers, NCSU-10 + DBA-4 displayed promising photovoltaic results and exhibited an enhanced PCE of 10.12 %. [48] The photovoltaic performances reported are of the DSSCsc o-sensitized using 0.2 mm of acceptor/anchoring groups.D BA-8 employed as ac o-sensitizer along with NCSU-10 broadened the spectral responses of the co-sensitized [49] Furthermore,A dhikari and co-workerss tudied the effect of anchoring/acceptor unit in the co-sensitizer using new indolebased co-sensitizers (N 1 ,N 2 ,a nd N 3 ;F igure 10) and co-sensitized with HD-14. [50] The co-sensitized system of HD-14 + N 3 showede nhanced J SC by nearly 10 %( i.e.,1 9.52 to 21.29 mA cm À2 ), resulting in PCEv alues up to 9.26 %.…”

“…DBA‐8 employed as a co‐sensitizer along with NCSU‐10 broadened the spectral responses of the co‐sensitized DSSC, thereby increasing light harvesting. Consequently, the device co‐sensitized using 0.2 m m DBA‐8 showed a maximum PCE of 10.68 % ( J SC =25.14 mA cm −2 , V OC =0.695 V, and FF=61.2 %) …”

New carbazole based dyes as effective co-sensitizers for DSSCs sensitized with ruthenium (II) complex (NCSU-10)

“…On the other hand, certain fascinating units such as cyanoacetic acid, catechol, salicylic acid and rhodanine substituents were used as effective acceptor/anchoring moieties in several reported sensitizers/co-sensitizers [24,25] . Recently, our group has established 4-aminobenzoic acid and barbituric acid as efficient acceptor/anchoring moieties in indole based dyes when used as co-sensitizers in devices [18,26] .…”
