Investigation of Light Absorption in Gold Nanoparticles Embedded Methylammonium Lead Iodide Perovskite Film

We investigate the inclusion of gold-nanoparticles of different sizes, and concentrations as light absorption enhancers in methyl-ammonium lead iodide (MAPbI
₃
) perovskite films, with the aim of establishing some guidelines for the future development of plasmonic resonance-based perovskite solar cells. We observe that the composite perovskite present the high light absorption coefficient for low concentration of gold-nanoparticles with small particles size. This study is important for the selection of matched concentration and size of gold or other metallic nanoparticles to design the efficient plasmon-enhanced organic-inorganic halide perovskite based solar cells and other optoelectronic devices.
