Abstract
In this work, by introducing Cu dopant, ultra-thin Ag transparent conductive films were prepared on glass and PET substrates without seed layers. The percolation threshold thickness for the Cu doped Ag thin films was as low as 6â¯nm with a RMS roughness only 0.19â¯nm. The prepared 6â¯nm Cu doped Ag thin films, Ag(Cu), had a transmittance of 80% at 550â¯nm and a sheet resistance of 14.1â¯Î©â¯sqâ1. The Ag(Cu) thin films revealed excellent thermal, chemical, and mechanical stability. Flexible polymer solar cells using the Ag(Cu) electrode reached a convert efficiency of 7.53% with a very thin PTB7-Th:PC71BM active layer. The proposed ultra-thin alloy transparent conductive films are ease of fabrication and beneficial to light harvesting, which are promising for large-area applications in flexible photovoltaics.
