Abstract

This paper describes synthesis of In2S3 nanoparticles by sonochemistry method and their application to enhance solar cells performance which In2S3 nanoparticles work as co-sensitizer for the first time. In2S3 is a narrow band gap semiconductor (2 eV) with conduction band higher than TiO2. Therefore it can transfer electron to the conduction band of TiO2. The effect of different parameters such as power and time on size of products were investigated. The fabricated solar cells made by different samples in the same conditions shown different Jsc, Voc, FF and efficiency. Modified dye sensitized solar cells (DSSC) exhibits the best performance with the power conversion efficiency of 8 % which is superior to that of the free–modified DSSC with the photoelectric conversion efficiency (PCE) of 5.1%. Modified solar cell shows 56.7% improvement in the efficiency. The prepared Nanoparticles and fabricated solar cells were characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM) and I-V measurement.
