Magnetic field effects in dye-sensitized solar cells controlled by different cell architecture

This paper investigates the effect of applying a static and dynamic magnetic field in the process of depositing the Fe-Cu compound on the working electrode of a dye-sensitized solar cell (DSSC). Depositing this compound on glass is especially hard due to the unfavorable layer inconsistencies that accompany the utilization of the doctor blade technique and the dissociation of the compound at a temperature of 700˚C, which prevents its ability to be evaporated or sintered beyond that temperature. The Fe-Cu compound is appreciably cheaper, relatively simple to produce and is more absorptive (>81%) in the Vis-NIR than the standard TiO2 mesoporous material normally used for DSSCs. The high diffusion of the Fe into the Cu lattice allows the compound to behave as a semiconductor and is found to have a bandgap of 1.8V. The sensitizer used in the production of a test cell consisted of a Schiff base dye with a compatible bandgap of 1.68 eV and resulted in more generated photocurrent than its TiO2 counterpart, which is a promising result for an alternative mesoporous layer in solar cells.

Sensitized Solar Cells

In this work, a magnetic polymer electrolyte composed by agarose as polymer matrix, NMP as solvent and NiO/TiO2mixed nanoparticles as modifier was investigated and employed in the solid-sate dye-sensitized solar cells (DSSCs). The influence of NiO/TiO2mixed nanoparticles on the morphology and ionic conductivity of the polymer electrolyte was studied by SEM and electrochemical impedance spectra. From SEM analysis, the mixing of NiO with TiO2nanoparticle in polymer electrolyte leads to smooth surface of the polymer electrolyte films. The polymer electrolyte modified by mixed nanoparticles with NiO: TiO2ratio of 1:4 shows the maximum ionic conductivity of 6.64×10-3S·cm-1. From photovoltaic performance study, the increase of NiO: TiO2ratio in polymer electrolyte leads to an improvement in light-to-electric conversion efficiency. The optimal photoelectric efficiency is achieved at NiO: TiO2ratio of 1: 4. Besides, after treatment under an external magnetic field, the DSSC modified with NiO: TiO2ratio of 1: 4 exhibits a better photovoltaic performance than that of DSSC without magnetic field treatment.
