Effect
of π‑Spacer Length in Novel Xanthene-Linked l‑(D−π–A)2‑Type
Dianchoring Dyes for Dye-Sensitized Solar Cells
Posted on 2022-06-01 - 16:05
The
effect of thiophene π-spacer length was studied in xanthene-linked l-(D−π–A)2-type dianchoring dye
performance in dye-sensitized solar cells. The photophysical, electrochemical,
and photovoltaic performances of KS-19 with single thiophene
and KS-21 with dithiophene units as π-spacers were
compared. The overall result showed that the presence of an extra
thiophene unit in KS-21 led to the extension of conjugation,
causing broadening and a red-shift of light absorption which in turn
resulted in increased JSC and power conversion
efficiency (PCE).
