Quasi Fermi Levels in Semiconductor Photovoltaic Heterojunction
... Values of F1n and F2p correspond to the shift of quasi Fermi Level of majority carriers electrons of side 1 and of holes of side 2 of heterojunction respectively. Under moderate illumination intensity, the relative changes of these majority carriers density are small in comparison to the correspondi ...

Density of states
.svg?width=300)
In solid-state and condensed matter physics, the density of states (DOS) of a system describes the number of states per interval of energy at each energy level that are available to be occupied. Unlike isolated systems, like atoms or molecules in gas phase, the density distributions are not discrete like a spectral density but continuous. A high DOS at a specific energy level means that there are many states available for occupation. A DOS of zero means that no states can be occupied at that energy level. In general a DOS is an average over the space and time domains occupied by the system. Localvariations, most often due to distortions of the original system, are often called local density of states (LDOS). If the DOS of an undisturbedsystem is zero, the LDOS can locally be non-zero due to the presence of a local potential.
