Enhanced performance of dye-sensitized solar cells with novel 2,6-diphenyl-4H-pyranylidene dyes

Publication year: 2011 Source: Organic Electronics, Available online 17 December 2011 Altan Bolag, Jun-ichi Nishida, Kohjiro Hara, Yoshiro Yamashita Novel 2,6-diphenyl-4H-pyranylidene derivatives were designed and synthesized as dyes for dye-sensitized solar cells (DSSC). Dyes2a,bwith a phenyl substituent showed high DSSC energy conversion efficiencies of 5.3% (Jsc = 10.3 mA/cm,Voc = 0.72 V, FF = 0.72) and 4.7% (Jsc = 8.9 mA/cm,Voc = 0.73 V, FF = 0.72) at 100 mW/cmunder simulated AM 1.5 G solar light conditions. These values are twice better than that of dye1without the phenyl substituent under the same conditions
