The amount of energy falling on the earth is given by the solar constant, but very little use has been made of solar energy…Why solar energy…???: Why solar energy…??? Largest source of energy SOLAR ENERGY= 100 X Daily consumption of 6 billion peoplePowerPoint Presentation: Source of Energy Consumption (EJ) Wind 2,250 EJ Biomass 3,000 EJ Solar 3,850,000 EJ Primary energy use 487 EJ Electricity 56.7 EJLight & the Photovoltaic effect: Light & the Photovoltaic effect Certain semiconductor materials absorb certain wavelengths - Shorter the wavelength, greater the energy - Ultraviolet light has more energy than infrared light Crystalline silicon - Utilizes all the visible spectrum plus some infrared radiationHow PV Cells Work?: How PV Cells Work?What are Solar Cells?: What are Solar Cells? Thin wafers of silicon - Similar to computer chips - Much bigger - Much cheaper Silicon is abundant(sand) - Non-toxic Light carries into the cell Cells convert solar energy into electric energy Sun light acts as the “fuel”How Solar Cells are made?: How Solar Cells are made?Solar Cell Construction: Solar Cell Construction Materials - Crystalline Silicon - Gallium Arsenide(More Expensive) Grown into large single-crystal ingots Sawed into thin wafers 2 wafers are bonded together (p-n junction) Wafers grouped into panels and arraysSolar PV Applications: Solar PV ApplicationsRecreational Use (Sail Boat): Recreational Use (Sail Boat)For residential purpose: For residential purposeFor commercial purpose: For commercial purposeConnecting PV to the Grid: Connecting PV to the GridThe massive source of energy…..: The massive source of energy…..Still a long way……: Still a long way…… You do not have the permission to view this presentation.
