analysis the photovoltaic thermal collector (PV/T) by Ansys and Radiation modle
 

Hi guys I am stuck and I could really use some help.
I want to do numerical study of photovoltaic thermal collector (PV/T) in fluent and I have already draw the PV collector with the thermal collector in Gambit.
I did the draw for the PV collector as the solid volume in gambit and mesh it with the thickness 4mm. and draw the thermal under the PV.
1- I have problem with the material for the PV model in fluent I must select the - Polycrystalline silicon photovoltaics. how can I add the properties for it.
2- the model must be radiation from the sun, which model I must to use and any solver.
3- if my draw in Gambit wrong, can I draw the PV collector in Gambit.

Thanks
