Iron pyrite (FeS2) is a promising earth-abundant semiconductor for thin-film solar cells. In this work, phase-pure, single-crystalline, and well-dispersed colloidal FeS2 nanocrystals (NCs) were synthesized in high yield by a simple hot-injection route in octadecylamine and then were subjected to partial ligand exchange with octadecylxanthate to yield stable pyrite NC inks. Polycrystalline pyrite thin films were fabricated by sintering layers of these NCs at 500−600 °C under a sulfur atmosphere.
黄铁矿 (FeS2) 是一种很有前途的丰富地球元素半导体，可用于薄膜太阳能电池。在这项工作中，通过十八胺中的简单热注射途径，以高产率合成了纯相、单晶和良好分散的胶体 FeS2 纳米晶体 (NC)，然后用十八烷硫醇进行部分配体交换，得到稳定的黄铁矿 NC 油墨。通过在硫气氛下在 500-600°C 下烧结这些 NC 的层来制备多晶黄铁矿薄膜。
