开发了一种透明的催化活性石墨烯纳米片（GNP）油墨，其适合于以0.4 m s（-1）的速度在柔性氧化铟锡基底上进行辊对辊印刷。使用这种墨水作为催化剂的染料敏化太阳能电池的效率为2.0%，而溅射铂的效率为2.6%。如果进一步优化，GNP油墨有可能取代化学还原或溅射铂。这将具有替代化学还原或溅射操作以及提供潜在的材料成本效益的益处。
A semitransparent catalytically active graphene nanoplatelet (GNP) ink was developed suitable for roll to roll printing onto a flexible indium tin oxide substrate at a speed of 0.4 m s(-1). Dye sensitised solar cells using this ink as a catalyst demonstrated efficiencies of 2.0%, compared with 2.6% for sputtered platinum. Given further optimisation, GNP inks have the potential to replace chemically reduced or sputtered platinum. This would have the benefit of replacing the chemical reduction or sputtering operations as well as providing potential material cost benefits.
