Some good info on CdS cells in this QEX article from NU1N:

I remember playing with a light-sensitive oscillator I put together
years ago. There was definately a lag between removing the light source
and the response of the oscillator--a second or two if I remember
correctly. I'm sure it could be used for communication, just so long as
you don't mind going really slowly. My guess is that the smaller the
component is the faster it will respond.
