Penyediaan dan pencirian sifat elektrik poli (3-tiopena asid asetik) dengan klorofil sebagai sel solar

Abstract

Poly (3-thiophene acetic acid) (P3 T AA), is presently considered as one of the most reliable emitting materials because of its excellent stability and luminescent properties is suitable to apply in many field including light sensor field or solar cell. The objective of this research is to prepare and characterize the P3 T AA/Chlo thin film as light sensor. It includes the preparation process of P3 T AA/Chlo thin film through the electrochemical method using Electrochemical Impedance Spectroscopy (EIS) and Spin Coating. P3 TAA/Chlo thin film was studied in electrical characterization. Four Point Probe was used to obtain the voltage value of P3 T AA/Chlo thin film for produce the conductivity value. The average conductivity of P3 T AA/Chlo thin film in the dark obtained was 0.0084 S/m and the higher value of conductivity under visible light intensity obtained was 0.094 S/m. From the graph, it was proven that conductivity of P3 T AA/Chlo thin film was increased when the intensity of light also increased. As conclusion, the P3 T AA/Chlo thin film was found suitable to be used as a light sensor or in the solar cell in the range of 10 W/m2 2 to 50 W/m of visible light intensity. It is recommend adding doping in P3 T AA/Chlo thin film in order to increase its conductivity, content and charge carrier types and to add range intensity of light on the high rate for producing the highest value of conductivity for used in a light sensor.
