摘要：

We report the synthesis of an amino acid viz. N-acetyle cysteine (NAC) assisted silver sulphide (Ag2S) nanoparticles by in situ reduction technique of silver nitrate (AgNO3) with sodium borohydride (NaBH4) in presence of NAC, where NAC acted as the sulphur donor as well as encapsulating agent. The prepared nanoparticles were characterized by transmission electron microscopy, scanning electron microscopy, atomic force microscopy, X-ray diffraction technique and dynamic light scattering technique. An enhancement was noticed in the current-voltage characteristics, with major reduction in reflectance when c-SiNx solar cells were coated with such nanoparticles. Broadband enhancement of external quantum efficiency (EQE) was also observed. (C) 2016 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V. All rights reserved.
