The fill factor of an image sensor array is the ratio of a pixel's light sensitive area to its total area. For pixels without microlenses, the fill factor is the ratio of photodiode area to total pixel area, [1] but the use of microlenses increases the effective fill factor, often to nearly 100%, by converging light from the whole pixel area into the photodiode.
The fill factor is directly affected by the values of the cell's series, shunt resistances and diodes losses. Increasing the shunt resistance (R sh) and decreasing the series resistance (R s) lead to a higher fill factor, thus resulting in greater efficiency, and bringing the cell's output power closer to its theoretical maximum.

There is an optimal load resistance that will draw the most power from the solar cell at a given illumination level. Shockley and Queisser call the ratio of power extracted to I sh V oc the impedance matching factor, m. (It is also called the fill factor.) The optimum depends on the shape of the I versus V curve.
Sometimes the overall sensor dimensions are given, from which the real estate area can be calculated. Whether the real estate area is given or derived, if the active pixel area is not given, it may be derived from the real estate area and the fill factor, where fill factor is the ratio of the active area to the dedicated real estate area.
Fill factor may refer to: Fill factor (solar cell), the ratio of maximum obtainable power to the product of the open-circuit voltage and short-circuit current. Fill factor (image sensor), the ratio of light-sensitive area of a pixel to total pixel area in an image sensor. In vision science, the ratio of view areas to the object visible areas.
Sphere packing finds practical application in the stacking of cannonballs. In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three- dimensional Euclidean space. However, sphere packing problems can be ...
The fill factor measures the ratio between the volume of a winding package and the volume needed to house the winding package. In case of stators, it can be said that the electrical fill factor is the ratio of the content of non-ferrous metals of the stator including the stator slot to the sum of the uninsulated copper cross sections.
In quantum mechanics, the energies of cyclotron orbits of charged particles in a uniform magnetic field are quantized to discrete values, thus known as Landau levels. These levels are degenerate, with the number of electrons per level directly proportional to the strength of the applied magnetic field. It is named after the Soviet physicist Lev ...
