Photovoltaics is the process of converting sunlight directly into electricity using solar cells. Today it is a rapidly growing and increasingly important renewable alternative to conventional fossil fuel electricity generation, but compared to other electricity generating technologies, it is a relative newcomer, with the first practical photovoltaic devices demonstrated in the 1950s.
The construction of a basic silicon solar cell is described, involving a p-type and n-type semiconductor material forming a PN junction. When light photons are absorbed by the semiconductor, electrons are energized and emitted, generating an electric current. Multiple solar cells can be connected in series, parallel or series-parallel

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. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
Multi-junction (MJ) solar cells are solar cells with multiple p–n junctions made of different semiconductor materials.Each material''s p–n junction will produce electric current in response to different wavelengths of light.The use of multiple

2. Solar cell design technologies. Two well-known solar cell design technologies employ the photovoltaic or photothermal mechanism for light harvesting. The first method directly converts the absorbed solar energy into electricity. In the second method, the absorbed energy is of the thermal type, and it is later converted into electrical energy.
