Key learnings: Solar Cell Definition: A solar cell (also known as a photovoltaic cell) is an electrical device that transforms light energy directly into electrical energy using the photovoltaic effect.; Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across
A solar cell can produce up to 2 W of energy. When load current is zero, its voltage becomes maximum and is known as open-circuit voltage V oc. When load current increases, short circuit current I sc is reached, and voltage becomes zero. Power from a solar cell shows a bell-type behavior between these two extremes of zero power.

The energy transformation in a solar cell involves converting light energy from the sun into electrical energy. This process is made possible by the photovoltaic effect, where photons from sunlight excite electrons in the solar cell''s semiconductor material, creating an electric current.
All PV cells have both positive and negative layers — it''s the interaction between the two layers that makes the photovoltaic effect work. What distinguishes an N-Type vs. P-Type solar cell is whether the dominant carrier of electricity is positive or negative. N-Type PV cells contain atoms with one more electron than silicon in the outer layer
Energy cannot be created or destroyed, meaning that the total amount of energy in the universe has always been and will always be constant. However, this does not mean energy is unchangeable. It can change form and even transfer between objects. A common example of energy transfer is the transfer of kinetic energy —the energy associated with motion—from
A solar cell turns sunlight into electricity through the photoelectric effect. Sunlight photons excite electrons in silicon cells, creating a flow of electricity. This electric current is then made suitable for homes or the grid.
