Solar photovoltaic electricity. When light is absorbed by matter, photons are given up to excite electrons to higher energy states within the material (the energy difference between the initial and final states is given by hν).
Photovoltaic cells turn sunlight into electricity using a semiconductor. They absorb photons, exciting electrons. These electrons are captured, creating electrical current. How do photovoltaic cells work? They absorb sunlight, knocking electrons free in a material. This flow of electrons makes electrical power, thanks to the cell’s electric field.
Photovoltaic technology changes light into electricity using materials that show the photovoltaic effect. It is key for solar power because it turns sunlight into clean electric power.
Solar cells are also key to exploring space. Fenice Energy is pushing boundaries with solar power that could meet global energy needs by 2030, even at just 20% efficiency. So, photovoltaic cells are setting the stage for a future where we sustain ourselves more cleanly and efficiently.
When the sun is rising, the photovoltaic (PV) cells begin generating an electrical current. This initiates a signal to the overall power system that electricity from the panels is available. Electricity produced by the solar panels will almost always take priority over grid-sourced electricity.
When the sun sets, the PV cells don’t have any work to do. But, that doesn’t mean that the solar-generated power stored throughout the day simply disappears.

When photons strike a PV cell, they will reflect off the cell, pass through the cell, or be absorbed by the semiconductor material. Only the photons that are absorbed provide energy to generate electricity. When the semiconductor material absorbs enough sunlight (solar energy), electrons are dislodged from the material''s atoms.

Introduction to Solar Cells
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
