Abstract

Semiconducting, octadecylamine (ODA)-capped, rod-like FeS₂ nanocrystals (NCs) are prepared and their properties are characterized. Transmission electron microscopy studies revealed the lattice fringes were clearly visible, confirming that the rod-like FeS₂ NCs obtained in this study were highly crystalline. X-ray diffraction (XRD) studies indicated that the structure of FeS₂ NCs is in cubic phase. Optical properties showed that the FeS₂ NCs can be a promising candidate for the electron acceptor material in the bulk hetero-junction (BHJ) solar cell applications. The power conversion efficiency of the BHJ solar cells using polymer and the rod-like FeS₂ NCs with a structure of glass /ITO/PEDOT:PSS/(FeS₂+polymer) /Al was found to be ∼0.45%.
