This Small Business Innovation Research Phase I project will develop high speed laser crystallization (HSLC) of solution deposited aluminum-doped zinc oxide (AZO) nanoparticle layers in order to reduce the manufacturing cost of thin film solar cells. AZO is a promising transparent conductive oxide (TCO). Deposition of TCO layers is one of the most expensive steps during the manufacturing process of thin film solar cells. Initial studies has already shown that HSLC crystallization of AZO layers yielded resistivity less than 3 x 10-4 ohms-cm and a maximum mobility of 380 cm2/vs (1-2 orders higher than the other deposition techniques such as sputtering). The proposed work will investigate high speed laser crystallization of AZO nanoparticles inks to prove the viability of high volume production of high performance TCO layers by HSLC of solution deposited nanoparticles. Technical milestones include: TCO deposition process speeds up to 2 orders faster over current techniques, transmission over 90% in 400-1500 nm range, and sheet resistance under 10 ohm/square. Scaling and optimization of the high-speed processes will be demonstrated on multiple large-area cells with a goal of a relative efficiency improvement of 5% over baseline cells using a sputtered AZO layer.The broader/ commercial potential of this project will be achieved through new equipment for integration into manufacturing to produce high-efficiency CIGS solar modules. Nearly half of the world?s CIGS solar manufacturing capacity has been established in the U.S. This SBIR development has the potential to improve manufactured CIGS solar cell efficiency by over 5% (relative) and reduce cost per watt by more than 10%. This would aid in moving flexible CIGS solar products into a market lead position, grow U.S. manufacturing, and enable large-scale adoption of solar. Integrating this technology into other PV device stack layers (such as the CIGS absorber layer) as well as the TCO layer, which is the subject of this proposal, could create over $4 billion in economic value annually by 2020. This process also has the potential to improve other commodity thin-film materials such as those used in lightweight paper batteries, organic solid state lighting, flexible displays, and RFID tags.

该小型企业创新研究第一阶段项目将开发溶液沉积铝掺杂氧化锌（AZO）纳米颗粒层的高速激光结晶（HSLC），以降低薄膜太阳能电池的制造成本。 AZO是一种很有前途的透明导电氧化物（TCO）。 TCO 层的沉积是薄膜太阳能电池制造过程中最昂贵的步骤之一。初步研究已经表明，AZO 层的 HSLC 结晶产生的电阻率小于 3 x 10-4 ohms-cm，最大迁移率为 380 cm2/vs（比溅射等其他沉积技术高 1-2 个数量级）。 拟议的工作将研究 AZO 纳米颗粒墨水的高速激光结晶，以证明通过溶液沉积纳米颗粒的 HSLC 大批量生产高性能 TCO 层的可行性。 技术里程碑包括：TCO 沉积工艺速度比现有技术快 2 个数量级，400-1500 nm 范围内的传输率超过 90%，薄层电阻低于 10 欧姆/平方。 高速工艺的扩展和优化将在多个大面积电池上进行演示，目标是使用溅射 AZO 层使基准电池的相对效率提高 5%。该项目的更广泛/商业潜力将通过集成到制造中的新设备来实现，以生产高效 CIGS 太阳能模块。全球近一半的 CIGS 太阳能制造能力已在美国建立。这项 SBIR 开发有望将制造的 CIGS 太阳能电池效率提高 5% 以上（相对），并将每瓦成本降低 10% 以上。这将有助于将灵活的 CIGS 太阳能产品推向市场领先地位，发展美国制造业，并实现太阳能的大规模采用。将该技术集成到其他光伏器件堆叠层（例如 CIGS 吸收层）以及 TCO 层（本提案的主题）中，到 2020 年每年可以创造超过 40 亿美元的经济价值。该工艺还具有改进其他商品薄膜材料的潜力，例如用于轻质纸电池、有机固态照明、柔性显示器和 RFID 标签的薄膜材料。
