Experiments on Photoconductivity
Kraftmakher, Yaakov
European Journal of Physics, v33 n3 p503-511 May 2012
Computer-assisted experiments with CdS and CdSe photoresistors are described. The most important characteristics of the photoresistors are determined: (i) the spectral response, (ii) the photocurrent versus incident radiant power, (iii) the rise and decay time constants and (iv) the frequency response to modulated light. The photoconductivity gain of the photoresistors is estimated. The experiments are well suitable for undergraduate laboratories. (Contains 5 figures.)
