A noble model for harvesting energy using piezoelectric material and solar panel: Bangladesh perspective

For the development of modern civilization huge amount of electrical power is necessary. To meet the demand of these power scientists is desperately searching for renewable and green sources of energy. This paper attempts to increase up the electrical energy using piezoelectric materials and solar panel together. Piezoelectric materials which can take mechanical stress and convert it to electrical energy and solar panel absorb the sun's rays as a source of energy for generating electricity. In this paper the output from solar panel has been added with outputs of piezoelectric material. Here piezoelectric material has been used in two ways. We have observed that huge energy was produced when piezoelectric crystals and transducer have been used to convert mechanical stress into electrical energy by using pressure and sound on it respectively. Crystals has placed on speed breakers of roadways and transducers have placed near roadside. The goal of this experiment is to generate power not only in day but also in night with the help piezoelectric materials, so that we get sufficient source of voltage to lighten up the street lights for distance than before.
