They then used pipettes to drop the silver wires, which were suspended in methanol, on to the surface of the strips.

然后用吸管将浸泡在甲醇中的银丝滴在棉布条的表面。

Co-extrusion also promises to improve the efficiency of solar cells by printing the silver wires that conduct current out of a cell.

共同挤压的方法也可以通过打印银线（作用是将电流传导出一块电池）来提高太阳能电池的效率。
