Synthesis of efficient bi-anchoring bifuran/biphenyl derivatives for dye-sensitized solar cell applications

Abstract

We have synthesized new metal-free dyes (HB-1–8) containing bifuran/biphenyl derivatives for dye-sensitized solar cells. Dye HB-3 exhibited the highest efficiency among the eight investigated dyes, reaching 5.51% with a VOC value higher than N3.

Delafossite CuCoO2/ZnO derived from ZIF-8 heterojunctions as efficient photoelectrodes for dye-sensitized solar cells

“… 9 O'Regan and Gratzel created the first DSSC in 1991. 10 The DSSC can typically create electrons by the absorption of light, transport the electrons upon application of high voltages, and then return the electrons to the device at low voltages. The photoanode working electrode, which is a mesoporous semiconductor film placed onto transparent, conductive glass (often fluorine doped thin oxide, FTO), the iodide/triiodide (I − /I 3 − ) redox electrolyte, and Pt counter electrode (cathode) are typically used to produce DSSCs.…”
