Abstract

Lampblack prepared by using a traditional mustard oil lamp was mixed with printer toner in the ratio of 1:1 by weight and the composite was used as a low-cost catalyst for the reduction of tri-iodide ions in dye-sensitized solar cells (DSCs). The X-ray diffraction (XRD) of the lampblack showed that the lampblack contains a carbonaceous material of graphitic form. The adhesion test of the composite film on the counter electrode (CE) of the DSC showed that the composite film is firmly attached on the CE. The DSC with CE based on the composite of lampblack and printer toner yielded the overall light to electricity conversion efficiency of 3.20 % compared with 4.18 % efficiency of the DSC with CE based on platinum when the solar cells were tested in the simulated light of 100 mW/cm2.
