Abstract A nano-particle solution processing route to the cost effective and easy fabrication of Copper Indium diSelenide (CIS) layers is presented in this study via the Electrospray Deposition of six different inks containing CIS nano-particle colloid solutions. Six different inks have been developed after synthesizing the CIS nanoparticles via solvo-thermal process. The inks differ from each other based on solvents and particle concentrations. Molybdenum coated glass was used as a substrate to deposit ~1 µm thick CIS layers. These deposited layers were then characterized according to their deposition parameters, surface morphology, structural analysis, transmittance behavior and electrical properties. Highly uniform chalcopyrite films were obtained with good purity and more than 90% absorbance characteristics with an average sheet resistivity of ~50 Ω.cm thereby confirming the applicability of the films to be utilized in the ultimate manufacture of solar cells.

纳米胶体油墨组成对高质量电喷涂铜铟二硒微膜制备及性能的影响

摘要 本研究通过含有 CIS 纳米颗粒胶体溶液的六种不同油墨的电喷雾沉积，提出了一种纳米颗粒溶液加工路线，可实现成本效益高且易于制造的铜铟二硒 (CIS) 层。通过溶剂热法合成 CIS 纳米粒子后，已开发出六种不同的墨水。基于溶剂和颗粒浓度，墨水彼此不同。钼涂层玻璃被用作基底来沉积 ~ 1 µm 厚的 CIS 层。然后根据它们的沉积参数、表面形态、结构分析、透射率行为和电特性来表征这些沉积层。
