This Small Business Innovation Research (SBIR) Phase I project addresses the need for a non-vacuum deposition approach for contact layers in CdTe solar cells. While sputtering is at present successfully employed, the objective of this project is the development of a nanoparticle ink that could be used to print submicron thick Te thin films. To date, Te inks produce non-uniform coatings owing to particle agglomeration. The research objective of this project is the formulation of a Te ink composed of dispersed, nonagglomerated Te particles with diameter less than 50 nm. The efficacy of this ink will be demonstrated by fabrication of CdTe solar cells as follows. First, the Te ink will be sprayed onto the CdTe layer of a solar cell heterostructure. Then, this green body will be subjected to a thermal treatment. Finally, the solar cell will be finished by deposition of an opaque electrode. Characterization will be performed on the ink, the sprayed layers, and the finished CdTe devices. If successfully developed, it is anticipated that this research would be translated to a production-sized (i.e., 100 megawatt) CdTe solar cell facility through the industrial subcontractor of this project.

这一小型企业创新研究(SBIR)第一阶段项目解决了对用于CdTe太阳能电池接触层的非真空沉积方法的需求。虽然目前溅射技术已被成功应用，但本项目的目标是开发一种可用于打印亚微米厚Te薄膜的纳米墨水。到目前为止，Te油墨由于颗粒团聚而产生不均匀的涂层。本项目的研究目标是研制一种由直径小于50 nm的分散的、不团聚的Te颗粒组成的Te油墨。这种墨水的功效将通过制作如下的CdTe太阳能电池来证明。首先，将Te墨水喷洒到太阳能电池异质结构的CdTe层上。然后，对这个绿色的车身进行热处理。最后，太阳能电池将通过沉积不透明电极来完成。将对油墨、喷涂层和成品CdTe器件进行表征。如果开发成功，预计这项研究将通过该项目的工业分包商转化为生产规模(即100兆瓦)的CdTe太阳能电池设施。
