While organic electronic devices mainly use organic or organic-inorganic hybrid materials, many electrodes still rely on pure metals due to their unparalleled electrical conductivity. Thus, the polymer-metal interface is crucial to device performance. Studies have demonstrated the use of ultrathin metal electrodes for (semi)transparent organic solar cells, and the quality of the interface influences the formation of structural defects, which can increase resistance and the likelihood of a short circuit. These metal contacts are typically deposited through lab-scale methods such as thermal evaporation, while industrial manufacturing prefers large-scale sputter deposition. Moreover, zwitterionic polymers can reduce the work function of metals and serve as interlayers in inverted organic solar cells. Therefore, understanding the growth behavior of sputtered silver on zwitterionic polymer surfaces is critical.
