Abstract

Chitosan is a natural polymer that is very common in many applications. In addition, Nicotine is a natural dye. To prepared Chitosan Nicotine (CN) layer we mix (1: 1) ratios from the Chitosan doping with Nicotine dye. After that, it is used as an active layer in solar cells. The morphology of the surface for the prepared layer is studied by scanning electron microscopy technique (SEM). From this study, We found that the surface of Chitosan could be more regular when it dopant with Nicotine than being a lone. The optical properties of samples were studied from UV-Visible spectra at wavelengths 300-900 nm. The analysis of optical measurements data showed that the absorbance increased after mixing the Chitosan with Nicotine. The parameters of solar cell were calculated within the voltage range (1-12Volt) and noted that the Short Circuit Current (JSC =1.6x10-3) mA/cm2, Open Circuit Voltage (VOC =7x10-2) V, Fill Factor (FF=0.51), Series Resistance (RS= 60) Ω and Shunt Resistance (Rsh= 250) Ω.were noted.
