Only protons of extremely high energy (many times the average energy in a star such as the Sun) are capable of producing nuclear events of this kind. A minimum temperature required for fusion is roughly 10 million K. Since the energies of protons are proportional to temperature, the rate of energy production rises steeply as temperature increases.

About Energy production of the sun

About Energy production of the sun

The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium.

This is the zone immediately next to the core, which extends out to about 0.7 solar radii.

This is the sun's outer layer, which accounts for everything beyond 70% of the inner solar radius (or from the surface to approx. 200,000 km below). Here, the temperatur.

Lastly, there is the photosphere, the visible surface of the sun. It is here that the sunlight and heat that are radiated and convected to the surface propagate out into space. Te.

The core of the Sun extends from the center to about 20–25% of the solar radius.It has a density of up to 150 g/cm(about 150 times the density of water) and a temperature of close to 15.7 million(K).By contrast, the Sun's surface temperature is about 5800 K. Recent analysis ofmission data favors the idea that the core is rotating faster than the radiative zone outside it. The Sun produces energy by nuclear fusion occurring in its core12. In this process, protons of hydrogen atoms collide and fuse to create helium atoms, releasing energy in the form of gamma rays2. The gamma rays are converted into thermal energy, heating up the core to around 15 million degrees Celsius2. The energy is then transferred from the core to the outer layers of the Sun, and escapes into space as sunlight1.

As the photovoltaic (PV) industry continues to evolve, advancements in Energy production of the sun have become critical to optimizing the utilization of renewable energy sources.
