Fabrication on plasmonic nanostructures as light trapper in perovskite and organic solar cells — •Tianfu Guan, Renjun Guo, Xinyu Jiang, and Peter Müller-Buschbaum — TU München, Physik-Department, LS Funktionelle Materialien, 85748 Garching, Germany

Photovoltaic technology that can converting sunlight directly into electricity is one of the most promising technologies to harvest solar energy for renewable electricity supply. For photovoltaics, such as organic solar cells (OSCs) and perovskite solar cells (PSCs), the light management is an essential issue for achieving higher efficiency and the utilization of plasmonic metal nanostructures has been demonstrated as a promising approach for enhancing light harvesting. In view of this point, to regulate the plasmonic spectral of gold nanoparticles (Au NPs) for maximizing the enhancement in light-absorption of active layer, we assembly the metal NPs onto the electron collecting layer to broaden absorption band of photoactive layer of OSCs and PSCs 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 metallic NPs will influence the crystallinity of the photoactive film and charge transportation of the device. In addition, grazing incidence wide angle x-ray scattering (GIWAXS) is used to probe the crystalline structure of the polymer/perovskite active layers. Grazing incidence small angle x-ray and neutron scattering (GISAXS and GISANS) is used to study the quality of the interface in terms of contact area between the materials.
