HYBRID PIEZOELECTRIC-SOLAR BASED ENERGY HARVESTING CARPET

Abstract

Hybrid Photovoltaic and Piezoelectric Energy Harvesting is an attractive method for clean energy production in areas with power shortage. The basic objective of the project is to prepare a small-scale standalone integrated energy harvesting system. A Hybrid system based on the integration of Photovoltaic and Piezoelectric Energy is to be developed. Solar Cell and Piezoelectric Transducers meet all energy requirements of the system. A mathematical module was developed for both the system in separate form and in integrated form as well in order to predict the effectiveness of the system under different working parameters. The model for piezoelectric was solved using MATLAB® software numerically. The verification of model was done by means of parametric analysis. The results of mathematical model were verified though simulations by using COMSOL® software and the optimum working conditions for the system were identified. COMSOL® utilized the Finite element method (FEM) to solve the computational model. In addition, the modelling of solar collector is done to evaluate the production of electric signal after the process of heating from Sun. This also became the basis of MATLAB® code, which demanded evaluation of versatile coefficients for various reasons. COMSOL Analysis for the stress analysis of Piezoelectric tells us the electricity production. A small-scale working prototype is to be developed to validate the theoretical results. It is finally concluded that the integrated energy harvesting model is a feasible and efficient way of harvesting energy.
