Novel modeling and analysis of the photovoltaic cell based on memristor characteristic

As a kind of neotype green energy resource,photovoltaic cell has been playing a significant role in alleviating the energy crisis and improving the ecological environment.Due to the mutability on the practical working condition and the uncertainty on the model parameters,this paper firstly presents two kinds of photovoltaic cell physical models based on nonlinear memristor,which is used to accurately describe the output characteristics of the actual photovoltaic cell with adaptive property.Meanwhile,the output characteristics of proposed photovoltaic cell models under different internal and external parameters are discussed with comprehensive theoretical derivation and numerical analysis,which is beneficial to choose the appropriate device parameters efficiently.Finally,a series of computer simulations are conducted to verify the effectiveness of the entire scheme.Notably,the proposed model provides convictive experimental basis and theoretical reference for the subsequent relevant application research.
