One should be using the correct terminology then. Sounds like disposal of used solar cells is not a huge problem, if the toxic components can be separated from the silicon and glass (which again is mostly silicon). Then its a matter of efficiency, whether it makes sense to recycle the silicon and glass or just grind and dump it.
I'm not sure that it's easy to separate out lead/cadmium from glass? I think I've heard that's also an issue with glass recycling in general. (certain though to break kitvhen/glassware also contain lead - and can't / shouldn't be recycled along with single use glass bottles).
