Organic DSSC Solar cell offers simple fabrication process, inexpensive, and clean. Moreover, the organic dye can be extracted directly from various plants is interesting from the industrial point of view. Recent works related to this field, suggest that different natural dyes sources result in different energy conversion efficiencies. For example, a dye extracted from carrot combined with TiO2 nanoparticle give as high as 0.00124% efficiency, which is considerably low for solar cell application. It was proposed to use Polyaniline (PANI) to increase the thermal stability of this kind of nanocomposites. PANI also provides a broad range of light absorbance, facile to synthesis, and tend to bond with a metal ion. Furthermore, PANI also possesses nice pore morphology and can be blended with another polymer. This work is designed to investigate the performance of TiO2PANI/ITO with different PANI concentration for solar cell device application. We prepared a TiO2-PANI paste then deposited onto ITO-Glass substrate with 0.25 cm2 active layer. TiO2-PANI/ITO-Glass was sintered at 450 °C for 1 hour and followed by dip coating process into dye aqueous of β-Carotene for 24 hours. The sandwich structure of DSSC was fabricated with I-/I3electrolyte, and carbon as the counter electrode. The resulted DSSC were characterized using FTIR, XRD, SEM, and I-V source meter. The solar cell parameters were obtained by employing a single diode model of Shockley equation via fitting procedures. The increase of PANI affected on the © 2019 The Authors.
