In this work the metal-polymer interface between gold contact and active layer of water-processed hybrid solar cells is investigated. The active layer consists of an aqueous soluble polythiophene and laser-ablated titania nanoparticles. Gold sputter deposition is applied to the active layer. To obtain full information of gold cluster growth kinetics during sputter process, in-situ time resolved grazing incidence small angle X-ray scattering (GISAXS) experiments and grazing incidence wide angle X-ray scattering (GIWAXS) are carried out. Different growth regimes of gold clusters are observed from the GISAXS and GIWAXS data analysis and discussed.
