Light Scattering Effect

The formation of a micro-crater structure with optimal morphology in a dye-sensitized solar cell (DSSC) improved the light scattering effect without an additional light scattering layer. In addition, it provided a wide entrance for a fast and complete electrolyte infiltration into the TiO2 film.

Sensitized Solar Cells

In this study, the flexible dye-sensitized solar cell is fabricated by pressurization-transfer technique, which involves assembling TiO2 films on ITO/PEN flexible substrates via high temperature sintering. During the experiment, we change not only the film thickness and structure of TiO2 but also the dye of working electrodes. The surface morphology of TiO2 films are examined by field emission scanning electron microscopy (FE-SEM). The analyses of UV-Vis show that N3 dye could be adsorbed on the TiO2 thin films, and the TiO2 thin film with scattering layer has better absorption than that of without scattering layer. The current-voltage of the DSSC is illuminated by the solar simulator whose incident light intensity was 1000 W/m2. These results indicate that the best efficiency of flexible dye-sensitized solar cell with high-temperature sintering TiO2 film and scattering layer is 6.13%.

In this work, several liquid electrolytes (LE) have been prepared. The electrolytes contain tetrapropylammonium iodide (TPAI) salt with different salt content, propylene carbonate (PC), ethylene carbonate (EC), polyethylene oxide (PEO), dimethylformamide (DMF) and (I-/I3-) redox couple LE was used in the Dye-Sensitized Solar Cell (DSSC). DSSCs were fabricated and current density-voltage (J-V) characteristics measured. The highest incident photon conversion efficiency (IPCE) at 520 nm is 45.5% for DSSC with 0.25 g TPAI LE. At AM 1.5, DSSC with LE exhibits efficiency of 6.61% with Jsc= 18.69 mA cm-2, Voc= 0.68V and fill factor (FF) = 0.52.

Indoline dyeD-1was successfully applied as a cosensitizer for improving the spectral response of black dye in dye-sensitized solar cells (DSCs). It was observed thatD-1effectively increases the short-circuit photocurrent by offsetting the competitive light absorption byI/I3-electrolyte in the wavelength region 350–500 nm when adsorbed on the TiO2nanocrystaline films in a mix dye system. The DSCs containing theD-1and black dye achieved a power conversion efficiency of 9.80% with higher short-circuit photocurrent of 19.54 mA/cm2compared to the system of black dye without cosensitization under standard AM 1.5 sunlight.

AbstractThis article presents the results of a research on the effects and properties of the potassium iodide additive onto the structure of the MEH-PPV polymer material, in its aspect of application in the dye-sensitized solar cell. Changes in MEH-PPV surface morphology were researched through increasing of the potassium iodide content measured by scanning electron microscope. The increased content of potassium iodide also led to increased electrical conductivity measured by the Keithley meter. The electrical properties of the dye-sensitized solar cell were also studied, in which the liquid electrolyte was replaced with a thin layer of polyelectrolyte, based on MEH-PPV and potassium iodide.
