Nonlinear dynamic instability of the perovskite solar cell under biaxial mechanical impacts

Abstract

The perovskite solar cell (PSC) is one of the most promising game-changers in the electro-optic market. This paper examines the nonlinear dynamic performance and stability of the PSC on elastic foundations under different support conditions subjected to various biaxial impacts. By incorporating the third-order shear deformation theory (TSDT) and von-Kármán geometric nonlinearity, the governing equations of the nonlinear dynamic analysis are deduced by employing the Galerkin method. By using the fourth-order Runge-Kutta approach, the nonlinear governing equations can be solved and subsequently, the dynamic buckling behaviour of the structure can be assessed. Multifaceted effects of the velocity impacts, boundary conditions, dynamic buckling criteria, initial imperfections, damping, elastic foundations, plate theories, and impulse loadings on mechanical performance and dynamic stability of the novel PSC are investigated in the numerical study. These numerical investigations inspire the holistic design of practical energy-harvesting devices with strengthened structure capacity against external impulses.
