Silicon is used in producing Pv celss because cells made from the crystallized polycrystalline silicon have efficiencies in the range of 14-18% and a moderate price.
If the container is closed, all vapor generated by boiling will stay in the container. If it is at constant volume, the pressure will rise in it. ... Heat pipes boil a liquid at one end and condense it at the other. So the system can remain closed because the contents don't increase: you put in heat, you take out heat.
