Finally, the cell bears an antireflective coating, which ensures that photons—the particles of sunlight needed to generate solar power—are absorbed by the silicon layers and not reflected away.

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

Chinese researchers have used metal-organic chemical vapor deposition (MOCVD) to produce a 12 cm2, five-junction solar cell with a minimal number of mismatch dislocations. The cell has an open ...

As the electrons flow through the cell, they generate electricity. On a much larger scale, solar-thermal power plants employ various techniques to concentrate the sun's energy as a heat source.

Most models of the solar system aren't completely accurate, and there's a good reason for that. It's not laziness or scientific misunderstanding - an accurate, to-scale portrayal of the solar ...

As the world anticipates the total solar eclipse on March 29 ... the moment the moon passes between the sun and Earth. The animation highlights the sun's corona, its outermost layer, visible ...
