Vibration and nonlinear dynamic response of nanocomposite multi-layer solar panel resting on elastic foundations

摘要

This paper dealt with the nonlinear dynamic response and vibration of multilayer organic solar panels subjected to mechanical and thermal loadings. The nanocomposite multilayer organic solar panel contains five layers which are manufactured by Al, P3HT: PCBM, PEDOT: PSS, Glass and Graphene which is a flexible replacement for indium tin oxide as a transparent and conducting electrode in the construction of solar panel. Based on classical theory, the basic equations are established by taking into account the effect of elastic foundations, von Karman nonlinearity terms, and initial imperfection. The closed form expressions of the frequency-amplitude curves and natural frequency are obtained by using the Galerkin and Runger-Kutta methods. The numerical results illustrate positive effect of elastic foundations, negative effect of temperature increment and initial imperfection, considerable influence of geometrical parameters as well as excitation force on the free vibration and dynamic response of multilayer organic solar panel.
