The influence of flexible dye-sensitized solar cell modified by different magnetic bead contents

In this study, the influence of different magnetic bead (MB) contents on photovoltaic efficiency of flexible dye-sensitized solar cell (DSSC) was investigated. MB was incorporated into TiO2 film by spin coating method. The short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (F.F.), and the photovoltaic conversion efficiency (η) of DSSC were measured by digital source meter and solar light simulator, which provided by a 1000 W Xenon (Xe) lamp to simulate sunlight under one sun AM1.5 G (100 mW/cm2) illumination. According to the experimental results, the DSSC modified by MB could improve many photovoltaic characteristics than modified by pure TiO2 working electrode.
