Synthesis and Dye-sensitized Solar Cell Application of Polyolefinic Aromatic Molecules with Pyrene as Surface Group

Abstract

Synthesis of polyolefinic aromatic molecules with pyrene as the surface group, and their role as an additive in the redox couple of dye-sensitized solar cells, is described. The studies yield a promising power conversion efficiency of 5.27% with a short circuit current density of 6.50 mA cm À2 , an open circuit voltage of 0.60 V, and a fill factor of 0.54 under 40 mW cm À2 simulated air mass (A.M.) 1.5 illumination. Most importantly, the photocurrent responsivity increases with an increase in the number of pyrene units on the surface.

Synthesis, photophysical, electrochemical, and DSSC application of novel donor–acceptor triazole bridged dendrimers with a triphenylamine core and benzoheterazole as a surface unit

“…Recently, we have used dendrimers as additives to improve the efficiency of DSSCs. In our laboratory dendrimers with dimethyl isophthalate 20 and pyrene 21 at the periphery have been used as additives in DSSCs. The present investigation mainly focuses on the synthesis, photophysical and electrochemical properties, and DSSC application of dendrimers 1-8 with a benzoheterazole surface group (Fig.…”

3-Pyrenylacrylates: Synthetic, Photophysical, Theoretical and Electrochemical Investigations

“…Its photophysical properties [1 -5] and its supramolecular chemistry [4 -9] have been widely studied. Structural modifications [10] allow for many applications, which include the development of fluorescent dyes [11], molecular electronics [2,12], optical sensors [13], fieldeffect transistors [13] and photovoltaic cells [14,15]. A wide range of fabrication techniques in combination with modern synthetic methods allow for the development of new materials which meet special demands and applications.…”
