单脉冲飞秒激光诱导的前向转移（LIFT，30 fs，790 nm）用于存款微米大小的点的铜和/或铟到玻璃上的钼层。这种系统可以作为前体，用于自下而上制造基于铜-铟-镓-二硒化物的微聚光太阳能电池。通过扫描电子显微镜、能量色散X射线分析和光学显微镜来鉴定铜、铟和组合的铜-铟供体层的厚度对转移点的质量的影响。证明了制造适于微聚光太阳能电池所需的微透镜阵列的几何形状的空间布置的潜力。
Single-pulse femtosecond laser-induced forward transfer (LIFT, 30 fs, 790 nm) is used to deposit micron-sized dots of copper and/or indium onto a molybdenum layer on glass. Such systems can serve as precursors for the bottom–up manufacturing of micro-concentrator solar cells based on copper–indium–gallium–diselenide. The influence of the thickness of the copper, indium, and combined copper–indium donor layers on the quality of the transferred dots was qualified by scanning electron microscopy, energy-dispersive X-ray analysis, and optical microscopy. The potential for manufacturing of a spatial arrangement adapted to the geometry of micro-lens arrays needed for micro-concentrator solar cells is demonstrated.
