Could anybody help to teach me how can I calculate the number of photon which a compund solution has absorbed from a visible light source?

I'm using a solution of graphene oxide quantum dots (GOD) to absorb the energy from a visible light source. The bandgap of GOD is 2.3 eV, the light source intensity is 40W/cm2. So how can I know...
