<p>A <b>photodiode</b> is a semiconductor <a href="page.php?w=diode">diode</a> sensitive to <a href="page.php?w=photon">photon</a> radiation, such as visible light, infrared or ultraviolet radiation, <a href="page.php?w=X-rays">X-rays</a> and <a href="page.php?w=gamma_rays">gamma rays</a>. It produces an electrical current when it absorbs photons. This can be used for detection and measurement applications, or for the generation of electrical power in <a href="page.php?w=solar_cells">solar cells</a>.
