Embodiments of the present application provide an array substrate, a fabrication method for an array substrate, and a display panel. The array substrate includes a substrate, a gate, a gate insulating layer, a seed layer, and a semiconductor layer that are sequentially stacked. A surface of the semiconductor layer away from the seed layer has a concave-convex structure formed by growth of nanocrystalline grains, which enhances light absorption of the semiconductor layer and solves the problems of poor light sensitivity and slow response speed of semiconductor devices.

Frontside metallization pastes for solar cell electrodes prepared from glass frit containing rare earth metals such as lanthanum and yttrium are disclosed. Electrodes prepared from the metallization pastes exhibit improved adhesion, reliability, and excellent electrical properties.

An image sensor includes a semiconductor material with a photodiode disposed in the semiconductor material. The image sensor also includes a transfer gate electrically coupled to the photodiode to extract image charge from the photodiode in response to a transfer signal. A floating diffusion is electrically coupled to the transfer gate to receive the image charge from the photodiode. At least one isolation structure is disposed in the photodiode, and the at least one isolation structure extends from a surface of the semiconductor material into the photodiode.

A method of generating electricity from light, that uses a photovoltaic array, that includes a junction between an inorganic electron-donating layer and an inorganic electron-accepting layer. The electron-donating layer includes moieties which after photon activation have unpaired electrons, and wherein some of the electrons are freed when light strikes the electron-donating layer, thereby transforming the moieties into free radicals or equivalents but many of the freed electrons recombine. Also, many of the free radicals or equivalents in the triplet state are optimally responsive to a selective magnetic field that has been determined to optimally increase the lifetime of the triplet state of the free radicals and thereby forestall recombination of the freed electrons into the free radicals. A magnetic field of substantially the optimal strength that is substantially unvarying over the electron donating layer is created as the array is being exposed to light.
