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 similar to 0.45%.
