Solar photovoltaic (PV) is the generation of electricity from the sun's energy, using PV cells. A Solar Cell is a sandwich of two different layers of silicon that have been specially treated so they will let electricity flow through them in a specific way. A Solar Panel is made up of many solar cells.

Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
Solar cells, also called photovoltaic cells, convert the energy of light into electrical energy using the photovoltaic effect. Most of these are silicon cells, which have different conversion efficiencies and costs ranging from amorphous silicon cells (non-crystalline) to polycrystalline and monocrystalline (single crystal) silicon types.

A photovoltaic cell alone cannot produce enough usable electricity for more than a small electronic gadget. Solar cells are wired together and installed on top of a substrate like metal or glass to create solar panels, which are installed in groups to form a solar power system to produce the energy for a home.
This conversion is called the photovoltaic effect. We''ll explain the science of silicon solar cells, which comprise most solar panels. A photovoltaic cell is the most critical part of a solar panel that allows it to convert sunlight into electricity. The two main types of solar cells are monocrystalline and polycrystalline.

Solar Photovoltaic (PV) cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many PV cells within a single solar panel, and the current created by all of the cells together adds up to enough electricity to help power your school, home and businesses.
Polycrystalline silicon photovoltaic panels: Polycrystalline silicon PV panels, also known as multi-crystalline cells, are made up of cells cut from an ingot of melted and recrystallized silicon. These ingots are then cut into extremely thin wafers and built into complete cells.
What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs.
Individual solar cell devices are often referred to as photovoltaic (PV) cells. A common single-junction silicon solar cell can produce a maximum open-circuit voltage of around 0.6-0.7 volts. Photovoltaic cells can serve as a building material, in addition to producing energy, due to their ability to be integrated into building structures.
There are many photovoltaic cells within a single solar module, and the current created by all of the cells together adds up to enough electricity to help power your home. A standard panel used in a rooftop residential array will have 60 cells linked together.
