The synthesized copper nanowires had much less oxide layer and stable surface layer for more than 100 days when stored in IPA solution. Cu nanowires with a diameter of 20-40 nm and length up to hundreds of micrometers, sometimes even around several millimeters, were manufactured through standard reaction condition. The roles of capping agents including Octadecylamine (ODA) were investigated. ODA as a capping agent provided mostly a uniform diameter to nanowires. In addition, a fairly suitable transparent electrode was prepared by the Cu nanowires having a high level of flexibility without breaking. Even after 500 cycles of bending, sheet resistance was from 36 Osq(-1) to 48 Osq(-1) with 90% transmittance. When applied to a flexible PEDOT:PSS/PTB7:PC70BM organic solar cell, it shows a high external quantum efficiency of 7.31%, which is a greatly enhanced result.
