You can do both, producing hydrocarbon fuels and carbohydrate calories, and also sequestering carbon. Maybe as diamonds, instead of soot to bury. Yes, you absolutely can trap much more CO2 per unit of collection area with photovoltaics than trees can manage. The trees are cheaper per unit of carbon capturing capacity, but what they bind the carbon into is less useful. That said, wood can be burned in such a way that only the hydrogen oxidizes, leaving charcoal that, powdered, can massively improve soil quality particularly in rainforests. Up until 500 years ago there was a thousands-of-years-long project doing this in the Amazon, interrupted by plague and collapse.
