The Sun does not have a definitive surface like the inner planets, rather, the density of the gas increases as you go down towards the core. I presume you are referring to the photosphere when you say 'surface'. In this case it is made of what the rest of the star is made of: Primarily hydrogen with some helium.
Hydrogen and helium held together by gravity and undergoing nuclear fusion. The surface in no different from the core, but it is much cooler.
Gases.
