Solar Cell: Basic Useful Physics Will Make You Understand It
A solar cell is an electronic device that directly converts sunlight into electricity. Light shining on solar cells produce both current and voltage.

Big Bang Theory: Singularity, Phases, Cosmic Microwave, Particle Physics, Hubble’s Law, Elements Abundances, Etc
The Big Bang Theory is a cosmological model of the observable universe from the earliest known periods through its subsequent large-scale evolution.
Steady-State Model of the Universe: Failure, Theory, Einstein, Cosmological Principle, General Relativity, Etc.
The steady-state model was proposed by three physicists in 1948, Hermann Bondi, Thomas Gold, and Fred Hoyle to explain the structure and working of Universe.
Spectroscopic Parallax: Useful Astrophysics Basics, Magnitude, Apparent, Absolute, Theory
Spectroscopic parallax is an astronomical method for measuring the distances to stars. It can be applied to any main sequence stars for which a spectrum can be recorded.
Radio Astronomy: Telescopes, Detection, Interferometry, Resolution, Drawbacks, Etc.
Radio astronomy is the sub-field of astronomy that studies celestial objects at radio frequencies. It was first used in 1932.
Visible Astronomy: Space Observatories, Telescope Types, Refracting, Reflecting, Hubble, Etc.
Visible light astronomy encompasses a wide variety of observations via telescopes that are sensitive to the range of visible light.
Solar System Formation: Disk, Solar Wind, Gases, Ices, Rocks, Accretion Disk, Temperature, Density, Planets, Asteroids, Ice Giants, Etc.
Historically, two basic scenarios of the origin of the Solar System have been discussed. In one, the Solar System formed as a byproduct of the Sun’s formation.
Black Holes Formation: Evolution, White Dwarf, Stars, Red Giants, Supergiants, Gravitational Collapse, Limit
When a main-sequence star has consumed the hydrogen the loss of energy generation causes gravitational collapse and star evolves off the main sequence.
Neutron Star Formation: White Dwarf, Black Hole, Supergiant, Chandrasekhar Limit
In 1934, Walter Baade and Fritz Zwicky suggested that Supernovae involve a collapse of a massive star, resulting in a neutron star.
Energy Generation in Stars: Sources, Nuclear Fission, Hydrogen, Nuclear Reaction, CNO Cycle
Two Energy sources are available to stars: Gravitational Contraction (Kelvin-Helmholtz) and Nuclear Fusion in the hot core.
