With
the aim of introduction a new inexpensive co-adsorbent to improve solar cell
performance, the influ-ence of nicotinic acid (NTA) used as a co-adsorbent in
dye-sensitized solar cells (DSCs) was investigated.
The
findings showed that low concentrations of NTA (<10 mM) increased the N719
ruthenium dye loading on the TiO2electrode surface by 10–12%, whereas higher
concentrations of NTA lowered the dye loading.
The
adsorption of NTA onto the TiO2electrode surface was studied by attenuated
total reflectance Fourier transform infrared spectroscopy and X-ray
photoelectron spectroscopy, and the blocking effect of NTA toward electron
transfer between the electrode and 1,4-dicyanonaphthalene (redox couple electrolyte
probe) was investigated by cyclic voltammetry.
Subsequently,
the performance of NTA in functional DSCs was evaluated by current–voltage
(J–V) DSC characterization and compared with that of DSCs fabricated with two
well-established co-adsorbents i.e., chenodeoxycholic acid (CDA) and
octadecylphosphonic acid (OPA).
The
findings showed that under optimized co-adsorbent concentration (1 mM NTA, 0.03
mM CDA, 0.015 mM OPA), the efficiency of the corresponding solar cells
increased to the same extent.
Specifically,
the use of NTA at optimum concentration improved the efficiency of the
resulting DSC from 3.14 to 5.02%.
