A Supply Energy System Based on Photovoltaic Panel with Two-Sided Mirror Coupled to a Harvester Piezoelectric Setup

Physics education in world regions where electrification is not 100% reached faces the challenge to offer high quality teaching of the energy concept with a focus on including learning opportunities for creating innovations while maintaining material costs low and thereby achievable. The aim of this work is to perform a prototype of an energy collector made up of two main parts. The first part is formed by the piezoelectric system which, under external pressure, generates energy passing through the rectifier bridge and stored in the battery. The second part is formed by the solar photovoltaic generator producing electrical energy improved by the two-sided mirror technique. The obtained results have shown that the two-sided mirror technique could improve the PV output power by 13.29%. The total energy produced is adapted for low loads power consumption like portable devices or even flashlight. The circuit diagram has been simulated in Proteus software with ARDUINO UNO microcontroller and experimentally realized. Our contribution can be one relevant cornerstone in supporting physics educators in all regions of the world to stimulate young generation toward green energy resources and thereby bring electric power in places where direct access to the power grid is not provided.
