Why and how:
Organic photodetectors (OPDs) are devices that convert light into an electrical signal. They are
made using organic materials, such as polymers or small molecules, which have the ability to
absorb light and generate charge carriers, such as electrons and holes. There are two types of
organic photodetectors such as photon based organic photodetector, and thermal organic
photodetector.
Organic photodetectors (OPDs) are gaining momentum due to their various advantages, such as
tunability of detecting wavelength, low-cost, compatibility with lightweight and flexible devices,
as well as ease of processing. They can be used in a wide range of applications, such as in
photovoltaics, environmental monitoring, imaging sensors, and optical communications. They
are also widely used in radiometry and photometry to calculate properties, such as optical
strength, luminous flux, optical intensity, and irradiance, in combination with other methods for
properties, including radiance.
OPDs operate by absorbing photons of light and generating charge carriers, which are then
transported to electrodes, where they are collected and converted into an electrical signal. The
efficiency of an OPD depends on several factors, such as the absorption spectrum of the organic
material, the charge carrier mobility, and the device architecture.
Increasing usage of fibre optic communication systems worldwide is accelerating the demand for
the organic photodetector owing to its good performance, small size, and low cost. Moreover, its
advantages such as low resistance, good spectrum response, long life, and low noise are
supporting the growth of the organic photodetectors market.
