1 giorno fa · The solar eclipse of April 8, 2024, also known as the Great North American Eclipse, was a total solar eclipse visible across a band covering parts of North America, from Mexico to Canada and crossing the contiguous United States. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the Sun.
1 giorno fa · Solar (and lunar) eclipses therefore happen only during eclipse seasons, resulting in at least two, and up to five, solar eclipses each year, no more than two of which can be total. [2] [3] Total eclipses are rarer because they require a more precise alignment between the centers of the Sun and Moon , and because the Moon's apparent size in the sky is sometimes too small to fully cover the Sun.
3 giorni fa · Perovskite solar cell bandgaps are tunable and can be optimised for the solar spectrum by altering the halide content in the film (i.e., by mixing I and Br). The Shockley–Queisser limit radiative efficiency limit, also known as the detailed balance limit, [105] [106] is about 31% under an AM1.5G solar spectrum at 1000 W/m 2 , for a Perovskite bandgap of 1.55 eV.

5 giorni fa · Solar storm puts on stunning display On the night of 10 May, Earth’s magnetic field got walloped by the Sun, as the planet experienced its most extreme geomagnetic storm since 2003 . The disturbance stemmed from a series of huge plasma expulsions from the Sun known as coronal mass ejections (CMEs), flung toward Earth by a sunspot cluster more than 15 times wider than Earth.
5 giorni fa · Sudair Solar PV is poised to become one of the largest single-contracted solar PV plants in the world and the largest of its kind in Saudi Arabia at an installed capacity of ~1,500MW. First project under The Public Investment Fund’s (PIF) renewable energy programme, the project has recorded the second lowest cost globally for Solar PV electricity production [USD 1.239 cents/kwh].
