One example is polymer
photodiodes with broadband absorption from 300 to 1,100nm.

photodiode with covered mesa structure," IEEE Transactions on Electron Devices, vol.
The open circuit voltage ([V.sub.oc]) and short circuit current ([I.sub.sc]) of the
photodiode under 100mW/cm illumination are given in Table 2.
Photodiode itself can function as a temperature sensor [21], but then it should run under no-load conditions (as opposed to the mode of
photodiode short circuit under the measurement of the UVR irradiance).
Photodiode sun sensors have been used often for spacecraft and satellite attitude determination systems [18,19].
The light box is designed to locate the
photodiodes. The light box was fabricated by using black colour acrylic with octagonal shape to provide better guide for
photodiode arrangement.
The
photodiodes feature a large (10 mm x 10 mm square) active area with room-temperature operation and a small detector footprint.
Optocouplers for analog signals galvanic isolation are formed on either side of the one LED and the other one
photodiode. These optocouplers, however, are inherently less linear and for galvanic isolation of analog signals not very appropriate.
Ophir-Spiricon has released their PD10-IR-pJ
Photodiode Energy Sensors, which measure very low energy to 30 pJ.
The ODD-470W is the first in a series of three new selective wavelength
photodiodes being introduced by Opto Diode.
The
photodiode array (PDA) detector for the TDAmax gel permeation chromatography (GPC/SEC) system from the company is said to provide a powerful and flexible tool for the rapid analysis of both polymers and biopolymers.
The
photodiode array detector provides noise specifications of 10 [micro]AU and data rates of up to 80 Hz.
