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.
The lighting ratio is the ratio of the light levels on the brightest-lit to the least-lit parts of the subject; the brightest-lit areas are lit by both key (K) and fill (F). The American Society of Cinematographers (ASC) defines lighting ratio as (key+fill):fill, or (key+Σ fill):Σ fill, where Σ fill is the sum of all fill lights.
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. [22] Typical fill factors range from 50% to 82%. The fill factor for a normal silicon PV cell is 80%.
Fill rate is different from service level. If a customer orders 1000 units, and their supplier can only provide 900 units of that order, their fill rate is 90%. In statistics, notably in queuing theory, service rate denotes the rate at which customers are being served in a system. It is the reciprocal of the service time.
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.
Fillrate or fill rate can refer to: Fillrate, a measure of graphics performance; Service rate, a logistics measure of ordering performance;

A dense packing of spheres with a radius ratio of 0.64799 and a density of 0.74786 [22] Many problems in the chemical and physical sciences can be related to packing problems where more than one size of sphere is available.
