INTRODUCTIONINTRODUCTION

Solar bicycle also known as solar e-bike is an electric Solar bicycle also known as solar e-bike is an electric bicycle with an electric motor which is driven by the use bicycle with an electric motor which is driven by the use of power from the battery which is being charged using of power from the battery which is being charged using solar energy by solar panels.solar energy by solar panels.

Photovoltaic (PV) cells contained in solar panels convert Photovoltaic (PV) cells contained in solar panels convert the sun's energy directly into electric energy are used.the sun's energy directly into electric energy are used.

It also uses a dynamo to charge the battery of the vehicle.It also uses a dynamo to charge the battery of the vehicle. They can travel up to 15 to 20 miles per hour (24 to 32 They can travel up to 15 to 20 miles per hour (24 to 32

Literature ReviewLiterature ReviewThe Photovoltaic EffectThe Photovoltaic EffectThe photovoltaic effect is the basic physical process through which a PV The photovoltaic effect is the basic physical process through which a PV cell converts sunlight into electricity. Sunlight is composed of photons--cell converts sunlight into electricity. Sunlight is composed of photons--packets of solar energy. These photons contain different amounts of packets of solar energy. These photons contain different amounts of energy that correspond to the different wavelengths of the solar energy that correspond to the different wavelengths of the solar spectrum. When photons strike a PV cell, they may be reflected or spectrum. When photons strike a PV cell, they may be reflected or absorbed, or they may pass right through. The absorbed photons generate absorbed, or they may pass right through. The absorbed photons generate electricity.electricity.The energy of a photon is transferred to an electron in an atom of the The energy of a photon is transferred to an electron in an atom of the semiconductor device. With its newfound energy, the electron is able to semiconductor device. With its newfound energy, the electron is able to escape from its normal position associated with a single atom in the escape from its normal position associated with a single atom in the semiconductor to become part of the current in an electrical circuit. semiconductor to become part of the current in an electrical circuit.
