Static buckling, vibration analysis and optimization of nanocomposite multilayer perovskite solar cell

In this study, analytical solutions for the static buckling and vibration analysis of nanocomposite multilayer perovskite solar cell (NMPSC) on elastic foundations are presented. The NMPSC consists of six isotropic layers which are including Au, PEDOT:PSS, perovskite, PCBM, ITO and glass. The basic equations are derived based on the Reddy's higher order shear deformation plate theory with the consideration of Pasternak-type elastic foundations interaction, von-Karman strain terms, initial imperfection and damping. The NMPSC is subjected to the uniformly distributed external pressure, axial compressive load and exposed to uniform temperature rise. The relationship between deflection amplitude and time, axial compressive loading and deflection amplitude, the frequency ratio and amplitude as well as the expressions of the natural frequency and critical buckling load are obtained by using Galerkin and Runge-Kutta methods. Bees Algorithm is used to maximize the natural frequency and critical buckling load of the NMPSC depending on ten geometrical and material parameters. The effects of temperature increment, elastic foundations, initial imperfection and geometrical parameters on the static buckling and vibration characteristics of the NMPSC are discussed through the parametric studies.
