By Finn Peacock, Chartered Electrical Engineer, Fact Checked By Ronald Brakels The photovoltaic effect is the fancy name given to the phenomenon of converting light to electricity in a conventional solar panel. Electricity is simply a flow of electrons running around a closed circuit.
Discovered in the 19th century, the photovoltaic effect occurs when photons, the particles that make up light, strike a material, causing the release of electrons. In solar panels, the photovoltaic effect occurs primarily in specially designed semiconductor materials, typically silicon.
The global expansion of solar photovoltaics (PV) is central to the global energy transition. As governments aim to triple renewable energy capacity by 2030, solar PV is poised for rapid growth, particularly outside mid-latitude regions (China, Europe, US) where uptake has been highest.
This effect is mainly activated by sunlight, although it can be triggered by natural or artificial light sources. However, in practice, the vast majority of photovoltaic panels use exclusively sunlight as an energy source.
The PV conversion is one of those phenomena in which light exhibits its particle-like nature. The physical effect taken advantage of in PV conversion is a version of the photoelectric effect (PE), called internal.
How does a solar panel work? Solar panels – also known as photovoltaic (PV) panels – are made from silicon, a semiconductor material. Such a material has some electrons which are only weakly bound to
Photovoltaic effect, process in which two dissimilar materials in close contact produce an electrical voltage when struck by light or other radiant energy. Light striking crystals such as silicon or germanium, in which
The Sunny Side: Photovoltaics Photovoltaic solar panels are in a class of their own for electricity generation. Most power sources turn a turbine and create current from a moving magnetic field. Solar panels go straight
The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within
Explore how the photovoltaic effect and solar energy physics convert sunlight into renewable electricity, powering a sustainable future with clean, efficient solar panels.

The photoelectric effect isn''t just a curious phenomenon—it''s the very mechanism that photovoltaic (PV) cells rely on to convert light into electricity. Semiconductors: The Crucial Middle Ground
How The Photovoltaic Effect Works By Finn Peacock, Chartered Electrical Engineer, Fact Checked By Ronald Brakels (the magic that makes solar panels work) The photovoltaic effect is the fancy
The photovoltaic effect is a fundamental phenomenon in the conversion of solar energy into electricity. It is characterized by the generation of an electric current when two different materials are in
The rated performance of solar PV modules (often referred to as solar panels) is defined using Standard Test Conditions (STC), which allow manufacturers to evaluate performance under simulated,
