A PRESENTATION ON SOLAR ENERGY.IT INCLUDES: AN INTRO HOW WE CAN GENERATE ELECTRICTY AND THE VARIOUS CONCEPTS UNDER ITS WORKING CONSTRUCTION OF SOLAR PANEL TYPES OF SOLAR PANEL BENEFTS OF USING SOLAR ENERGY HOPE YOU FRIENDS LIKE MY WORK.

1. SOLAR ENERGY

2. SOLAR ENERGY
➢Solar energy is radiant light and heat from the sun
generating electricity.
➢It is the mostcleanest and most abundant renewable
energy.
➢Solar energy is the cheaper than fossils fuels.
➢Karnatka is the largestsolar energy producer in India.

3. ➢Our sun is a nuclear reactor.
➢It releases tiny packets of energy called PHOTONS.
➢Photon hit a solar cell, they knock electrons loose from
their atoms.
➢If conductors are attached to the +ve and –ve sides of a
cell,it form an electrical circuit.
➢When electron flow through such a circuit, they generate
electricity.

5. Solar panels are made up of silicon

6. SILICON :A SEMICONDUCTOR

7. DOPPING
In semiconductor production, doping is the intentional introduction
of impurities into an intrinsic semiconductor for the purpose of
modulating its electrical, optical and structural properties

8. PN JUNCTION

10. CONSTRUCTION OF SOLAR PANEL

11. TYPESOF SOLAR PANELS
MonoCrystallinepanel:If you see a solar panel with black cells, it’s most likely a
monocrystalline panel. These cells appear black because of how light interacts
with the pure silicon crystal
Polycrystallinepanel: Unlike monocrystalline solar cells, polycrystalline solar cells
tend to have a bluish hue to them due to the light reflecting off the silicon
fragments in the cell in a different way than it reflects off a pure monocrystalline
silicon wafer.
Thin-Filmsolar panel:The biggest differentiating aesthetic factor when it comes to
thin-film solar panels is how thin and low-profile the technology is. As their name
suggests, thin-film panels are often slimmer than other panel ty[es. This is
because the cells within the panels are roughly 350 times thinner than the
crystalline wafers used in monocrystalline and polycrystallinesolar panels.
