薄膜CIGS技术由于其潜在的低成本和最佳性能而备受关注。如果小段串联互连以减少薄膜中的光电流和电阻损耗，则可以保持具有大面积的电池的效率，并且激光划片工艺对器件的性能至关重要。我们提出了我们的研究结果，CIGS薄膜太阳能电池与单个和多个平行的激光束与皮秒脉冲宽度的划片。太阳能电池的性能测试之前和之后进行激光划片与拉曼光谱分析。用光学显微镜和扫描电子显微镜评价加工质量。
The thin-film CIGS technologies for photovoltaics are attractive due to their potential low cost and optimal performance. Efficiency of cells with a large area might be maintained if small segments are interconnected in series in order to reduce photocurrent in thin films and resistance losses, and laser scribing process is crucial for performance of the device. We present our results on scribing of CIGS thin-film solar cells with single and multiple parallel laser beams with the picosecond pulse duration. Solar-cell performance tests were performed before and after laser scribing together with Raman spectroscopy analysis. The quality of processing was evaluated with optical and scanning electron microscopes.
