Plasmonic metal-dielectric composites have fascinated a great interest in various fields, owning to surface plasmon resonance (SPR) induced by incident radiation. The utilization of plasmonic metal nanoparticles (NPs) is frequently proposed as a means to further enhance the light absorption in the broad wavelength range as well as to facilitate charge collection and transport in the Perovskite solar cells (PSCs). To regulate the plasmonic spectral of Au NPs for maximizing the enhancement in light-absorption of the photoactive layer, we assembly the metal NPs onto the electron collecting layer to broaden the absorption band of the photoactive layer of optoelectronic devices as well as enhance the device performance. To meet the optimal results, we put effort into the plasmonic structure regulation, since the size, density, and morphology of the Au NPs will influence the crystallinity of the perovskite film and charge transportation of the device. Besides, grazing incidence small angle x-ray scattering (GISAXS) is used to study the quality of the plasmonic structure interface in terms of contact area between the perovskite film. Grazing incidence wide angle x-ray scattering (GIWAXS) is used to probe the crystalline structure of the perovskite active layers.
