摘要

在柔性不锈钢箔衬底上激光切割铜铟镓硒（Cu(In, Ga)Se2， CIGS）薄膜太阳能电池，可以充分利用其灵活性潜力，但由于热效应而存在失效的风险。在这项研究中，我们使用紫外纳秒脉冲激光来检验激光切割CIGS电池以实现无损效率的可行性。我们发现，通过冷切割或汽化切割进行激光切割可以实现这一目标。通过冷激光切割，面积为1 cm2的CIGS太阳能电池最高效率可达95.7%。即使电池面积减小到0.25 cm2，电池效率仍然高达84.7%。该研究为柔性CIGS太阳能电池在金属基板上的广泛应用铺平了道路。

Ultraviolet nanosecond laser-cutting mechanisms of flexible stainless steel-based Cu(In, Ga)Se2 solar cells

Laser cutting of copper indium gallium selenide (Cu(In, Ga)Se₂, CIGS) thin-film solar cells on flexible stainless steel foil substrates allows the advantage of fully exploiting its flexibility potential but presents a risk of failure due to thermal effects. In this study, we used an ultraviolet nanosecond pulsed laser to examine the feasibility of laser-cutting CIGS cells to achieve lossless efficiency. We discovered that this goal can be realized when laser cutting is performed by cold or vaporization cutting. By cold laser cutting, CIGS solar cells with an area of 1 cm² can achieve a maximum efficiency of 95.7%. Even when the cell area is reduced to 0.25 cm², the cell efficiency remains as high as 84.7%. This study paves the way for versatile applications of flexible CIGS solar cells on metal substrates.
