What Does PCD Stand For?
PCD stands for Photoconductive Decay
Photoconductive Decay (PCD) refers to the phenomenon where the conductivity of a material decreases over time after exposure to light. This effect is commonly observed in photoconductive materials, which initially exhibit an increase in electrical conductivity when illuminated but gradually return to their original state as the photogenerated carriers recombine or are trapped. Understanding PCD is essential in fields such as optoelectronics, photovoltaics, and sensor technology, as it impacts the performance and efficiency of devices that rely on light-responsive properties.
