This Small Business Innovation Research (SBIR) Phase I project aims to develop nickel-based nanoinks for the front-side metallization of silicon solar cells. Current front-side metallization processes rely on screen printing contact methods that use silver paste, which contains glass frits that require high curing temperatures from 800 to 900 degree Celsius. The high temperatures introduce stress on the silicon wafer and the contact method risks cracking the wafer. In this project, nanonickel inks will be synthesized and deposited on solar panels by a non-contact Aerosol-Jet method at low temperatures from 300 to 400 degree Celsius. The nanonickel inks will be used as a seed layer for front-side metallization of solar panels. An additional layer of copper nanoinks will be deposited on top of the nickel layer creating thicker conductive lines. The broader/commercial impact of this project will be the potential to offer a cost-effective replacement to silver paste for the front-side metallization of crystalline-silicon solar cells using a non-contact method. It is expected to provide manufacturing processes and materials that enhance quality of front-side metallization while reducing cost.

该小型企业创新研究 (SBIR) 第一阶段项目旨在开发用于硅太阳能电池正面金属化的镍基纳米油墨。目前的正面金属化工艺依赖于使用银浆的丝网印刷接触方法，其中含有玻璃料，需要 800 至 900 摄氏度的高固化温度。高温会给硅晶片带来应力，接触方法有使晶片破裂的风险。在该项目中，将在300至400摄氏度的低温下通过非接触式气溶胶喷射方法合成纳米镍墨水并将其沉积在太阳能电池板上。纳米镍油墨将用作太阳能电池板正面金属化的种子层。额外的铜纳米油墨层将沉积在镍层的顶部，形成更粗的导电线。该项目的更广泛/商业影响将是有可能为使用非接触方法的晶体硅太阳能电池的正面金属化提供具有成本效益的银浆替代品。 预计将提供提高正面金属化质量同时降低成本的制造工艺和材料。
