There is a glass shader in the material library based on the principled shader….you can start with that.
some crazy stuff, work and fun….

I think you are referring to the blackness behind the glass
the easiest way to solve that is to exclude your glass from shadow casting
or you can play with faux caustics parameters to get some varying amount of shadowing based on light angle
or directly modify shader to alter opacity for shadow rays any way you want
or more expensive way is to actually render with caustics through caustic light
the most expensive would be turning on All Paths on mantra and making sure the diffuse limit is at least 1, but that would be probably too noisy as mantra doesn't do VCM yet

Hahaha, yes. I didn´t realize what the original post was really asking. Definitely Faux Caustic is your friend…is fast and quite good.
