Experiment: Photoconductivity (230 V, 50/60 Hz)

Experiment: Photoconductivity (230 V, 50/60 Hz), 8000776 [UE6020400-230], Conduction Phenomena
Objective: Record the characteristic curve for a photoresistor

Photoconductivity utilises absorption of light by means of the inherent photoelectric effect in a semiconductor to create electron-hole pairs. One specific semiconductor mix which exhibits the photoelectric effect particularly strongly is cadmium sulphide. This material is used in the construction of photoresistors. In this experiment, a CdS photoresistor is illuminated with white light from an incandescent bulb. The intensity of this illumination of the photoresistor is then varied by crossing two polarising filters placed one behind the other in the beam.
