Sulfobetaine-based polyzwitterions are efficient interlayers for organic photovoltaics, but their polymer-metal interfacial morphology remains elusive. Moreover, plasma pretreatment of organic solar cells can bypass operational degradation from prolonged light exposure. By in-situ grazing incidence small angle X-ray scattering, we probe the evolution of gold cluster growth on thin polysulfobetaine films during metal sputtering, the latter being an industrially-relevant metal deposition technique. We present differences on the sputtered gold nanostructural morphology with and without oxygen plasma pretreatment.
