The photovoltaic effect is a fundamental phenomenon in the conversion of solar energy into electricity is characterized by the generation of an electric current when two different materials are in contact and exposed to light or electromagnetic radiation.. This effect is mainly activated by sunlight, although it can be triggered by natural or artificial light sources.
Solar radiation includes three main types: ultraviolet (UV) radiation, visible light, and infrared (IR) radiation. UV radiation, though a small part of the spectrum, is powerful and responsible for effects like sunburn.

Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.This phenomenon was first exploited in 1954 by scientists at Bell Laboratories who created a working solar cell made from silicon that generated an electric current when exposed to sunlight.
Solar radiation, the radiant energy emitted by the sun, serves as the primary source of energy for PV systems. Understanding the characteristics of solar radiation, including its intensity, spectrum, and variability, becomes paramount in optimizing the performance of photovoltaic cells.
The dependence on sunlight restricts the output potential of solar plants to 35% – 40%. Solar energy is heavily dependent on government subsidies, so this questions the economic reliability of the industry. Reducing the cost of solar energy systems with subsidies using taxpayer money is not exactly reducing anything.

Definition of solar radiation: Solar radiation is the radiant energy emitted from the sun, encompassing the complete frequency spectrum of electromagnetic radiation, including visible light, and near-visible radiation (UV Rays, Infrared Rays, X-rays, etc.).
It powers crucial biological and physical processes that sustain life. For instance, solar radiation is directly responsible for photosynthesis, the process by which plants convert sunlight into energy, producing oxygen and serving as the foundation of most food chains.
Disadvantages of solar energy Solar panels are not useful when it is cloudy (which means solar farms are more effective in places with less cloud cover). Solar panels generate no electricity at night time. Solar panels can't store energy, so you have to use the electricity they generate when the sun is shining.
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors.
