据报道，玻璃和柔性塑料基板上的银栅电极的性能超过了商用氧化铟锡（ITO）涂层玻璃，并显示其适合作为溶液处理有机光催化剂（OPV）中ITO玻璃的直接替代品。当支撑在柔性塑料基板上时，这些电极在数万次循环中通过小曲率半径的重复弯曲是稳定的。网格电极是由冷凝系数调制的非常规方法，使用全氟化聚合物显示出远远上级用于此目的的其他化合物的日期。可以实现的非常窄的线宽和小的网格间距也为在OPV中使用网格电极的可能性打开了大门，而无需导电聚（3，4-亚乙基二氧噻吩-聚（苯乙烯磺酸盐））（PEDOT：PSS）层来跨越网格线之间的间隙。
Silver grid electrodes on glass and flexible plastic substrates with performance that exceeds that of commercial indium‐tin oxide (ITO) coated glass are reported and show their suitability as a drop‐in replacement for ITO glass in solution‐processed organic photovoltaics (OPVs). When supported on flexible plastic substrates these electrodes are stable toward repeated bending through a small radius of curvature over tens of thousands of cycles. The grid electrodes are fabricated by the unconventional approach of condensation coefficient modulation using a perfluorinated polymer shown to be far superior to the other compounds used for this purpose to date. The very narrow line width and small grid pitch that can be achieved also open the door to the possibility of using grid electrodes in OPVs without a conducting poly(3,4‐ethylenedioxythiophene‐poly(styrenesulfonate) (PEDOT: PSS) layer to span the gaps between grid lines.
