Efficiency improvement of crystalline silicon solar cells
... significantly reduces the emitter saturation current (Joe) and therefore leads to a higher short circuit current [5]. The passivation is characterized by measuring the Si-H and N-H concentrations in the SiNx layer [39, 40]. In case of optical efficiency, SiNx layer with higher RI gives higher extinc ...

... The electrolysis of water differs in two important ways from “ordinary” chemical reactions. First, in an “ordinary” chemical reaction the electrons are transferred directly, by physical contact between the reacting species. In the electrolysis reaction, however, the electrons are transferred indirec ...

... That is, at least for spheres of constant density, as a star (or protostar) in hydrostatic equilibrium contracts its central temperature rises as the cube root of the density. It also says that stars (or protostars) will have a higher temperature at a given density if their mass is bigger. In the ab ...

Microplasma
Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
