Dye-sensitized solar cell (DSSC) provides high ability of renewable energy generation. One the main factors affects performance DSSC is type dye applied as a sensitizer. Natural sensitizers have become major concern due to widely availability in world and environmentally friendly characteristic. However, need improve natural dyes based very important. This review was conducted present recent st...

In this study, we fabricate a counter electrode by coating Pt ribbon onto fluorine-doped tin oxide glass substrate with layer. The gives rise to protrusive structure of the electrode, produced photolithography, sputtering and lift-off processes. experimental results reveal that photoelectric efficiency dye-sensitized solar cell (DSSC) (5.32%) is 21% higher than DSSC without (4.38%). This infers...

Nickel phosphide-embedded graphene, prepared by the hydrothermal reaction of red phosphorus, nickel chloride, and graphene oxide in a mixture of ethylene glycol-water, is investigated as the counter electrode of DSSCs. It is demonstrated that the DSSC with the nickel phosphide-embedded graphene as the new counter electrode presents an excellent performance competing with that of the Pt electrode.

We have synthesized soluble TiOPc derivatives containing alkoxy groups for use as additives in dye-sensitized solar cells (DSSCs). The DSSC devices containing these TiOPc derivatives exhibited short-circuit current densities of 8.49~10.04 mA/cm(2) and power conversion efficiencies of 2.73~3.62 % under AM 1.5 illumination and 100 mW/cm(2) irradiation.

We report the first case of Ru(II) dipyrrinates employed as dyes in dye-sensitized solar cells. These complexes exhibit panchromatic light harvesting that results in significant DSSC current densities, rendering them promising for photovoltaic applications. Adjustment of the lowest excited state energy is required to boost the power conversion efficiency.

Wurtzite and kesterite Cu2ZnSnS4 (CZTS) nanocrystals were employed as counter electrode (CE) materials for dye-sensitized solar cells (DSSCs). Compared to kesterite CZTS, the wurtzite CZTS exhibited higher electrocatalytic activity for catalyzing reduction of iodide electrolyte and better conductivity. Accordingly, the DSSC with wurtzite CZTS CE generated higher power conversion efficiency (6.8...

A new series of neutral, thiocyanate-free Ru(II) sensitizers (TFRS-1-3), which are assembled using both 4,4'-carboxy-2,2'-bypyridine and 2-pyridyl pyrazolate ancillaries, exhibit a light-harvesting capability up to 700 nm and superior DSSC performance in conversion efficiency (eta = 9.54% for TFRS-2).

We have succeeded in fabricating a high-performance DSSC with a light-to-electric energy conversion efficiency of 12.8% under one sun simulated solar irradiation.

A chemically sintered and binder-free paste of TiO2 nanoparticles (NPs) was prepared using a binary-liquid mixture 1-octanol CCl4. The 1:1 (v/v) complex CCl4 easily interacted with the NPs induced formation highly viscous paste. as-prepared (<bold>P</bold>BL)-based film exhibited complete removal residuals subsequent low-temperature sintering (~150°C) UV-O3 treatment. This facilitat...
