摘要

我们报道了一种完全集成的小分子有机p-i-n串联太阳能电池的卷对卷真空生产工艺。太阳能箔是在柔性PET基板上制备的。采用三种不同的激光工艺对透明底触点、有机层和金属顶触点进行了制模。对于生产工具的升级阶段,开发了一种简化的有机堆栈,以达到5%以上的效率,且复杂性适中。Heliatek的卷对卷生产模块在1033cm2的有效面积上显示出高达6.8%的效率,填充系数为65.4%。在批量制备的小样品上堆叠相同层的实验室模块在所有电参数上达到大致相同的值,证明了真空沉积制备的小分子p-i-n串联太阳能电池的优异可扩展性。

Organic solar cells: from lab to roll-to-roll production
We report on a fully integrated roll-to-roll vacuum production process of small-molecule organic p-i-n tandem solar cells. The solar foils are prepared on a flexible PET substrate. Three different laser processes were developed to pattern the transparent bottom contact, the organic layers and the metal top contact. For the ramp up phase of the production tool, a simplified organic stack was developed to reach efficiencies above 5% with moderate complexity. The modules from Heliatek’s roll-to-roll production show efficiencies of up to 6.8% on the active area of 1033cm2 with a fill factor of 65.4%. Lab modules with the same layer stack on smaller samples prepared in a batch to batch process reach about the same values in all electrical parameters proving the excellent scalability of small-molecule p-i-n tandem solar cells prepared by vacuum deposition.
