An option that specifies how full the database should make each index page. The amount of empty space on an index page is important because when an index page fills up, the system must take time to split it to make room for new rows. Use a fill factor of zero (0) to accept the database default.
The ratio of maximum power to the product of open-circuit voltage and short-circuit current. Fill factor is the "squareness" of the I-V curve shape.
the ratio of light-sensitive area to the pixel's total size; also known as aperture efficiency. The layout, or "designed fill factor," typically underestimates the effective fill factor, because the transistor regions of the pixel can also contribute signal.
As relates to the light gathering area of a sensor such as a CCD. For example, 10% of a pixel's area may be used to conduct the charge out of the pixels there, making this area insensitive to light. Therefore, in this example, the CCD sensor would only have a 90% fill factor.
The ratio of the light sensitive area to the pixels total size. If a pixel size is 17 microns and has a fill factor of 60%, this means the photo sensitive area exposed to light is 10.2 microns. The 40% area not sensitive to light has metal interconnect or other structures within the pixel design that obscures light. The fill factor can be further defined in terms of X & Y fill factor.
A term that relates to the light-gathering area of a CCD. For instance, a CCD with 90% fill factor has an imaging array in which 10% of each pixel's area is insensitive to light. Most of the CCDs (except interline CCDs) have 100% fill factor.
The ratio of a photovoltaic cell's actual power to its power if both current and voltage were at their maxima. A key characteristic in evaluating cell performance.
The fill factor is defined as the ratio of the maximum power (Vmp x Jmp) divided by the short-circuit current (Isc) and open-circuit voltage (Voc) in light current density - voltage (J-V) characteristics of solar cells.
