PV Cells 101: A Primer on the Solar Photovoltaic Cell
Then the current flows through metal contacts—the grid-like lines on a solar cell—before it travels to an inverter. The inverter converts the direct current (DC) to an alternating current (AC), which flows into the electric grid and, eventually, connects to the circuit that is your home''s electrical system. As long as sunlight

How do solar panels work?
The diode is sandwiched between metal contacts to let the electrical current easily flow out of the cell. About 95% of solar panels on the market today use either monocrystalline silicon or polycrystalline silicon as the semiconductor.
How is a silicon solar cell made?
To make a silicon solar cell, blocks of crystalline silicon are cut into very thin wafers. The wafer is processed on both sides to separate the electrical charges and form a diode, a device that allows current to flow in only one direction. The diode is sandwiched between metal contacts to let the electrical current easily flow out of the cell.
What is the difference between a solar cell's fingers and busbars?
Both the fingers and the busbars are electrical conductors. The fingers, or finger-like contacts, are thin, metallic lines that collect and deliver energy from the solar cell to the busbars. Busbars, typically made of aluminum or silver-plated copper, run perpendicular to the fingers.
