Geometrically nonlinear dynamic analysis of the stiffened perovskite solar cell subjected to biaxial velocity impacts

Abstract The perovskite solar cell (PSC) is one of the most promising photovoltaic candidates along with highly increasing demand for green electricity. One main concerns regarding PSC during its service life nonlinear instability due to ultra-thin structural features and dynamic loadings. This paper presents a framework stability analyses oblique stiffeners that are integrated as enhancements against external impacts. Considering von-Kármán geometric nonlinearity smeared stiffeners, governing equation derived by capitalizing on Airy’s stress function Galerkin approach. deduced motion can be effectively solved fourth-order Runge–Kutta method, such natural frequency, wind-induced vibration behaviour, buckling characteristics stiffened assessed. accuracy developed verified established benchmarks. Moreover, effects damping ratio, thermal variance, wind load, compression speed, elastic foundation, initial imperfection, active layer thickness response thoroughly examined. Concluding remarks, drawn from this study, mechanical performance novel will benefit practical design application energy harvesting devices.
