This outermost shell would be the least powerful but also the most materially expensive to construct, due to size.
It is incredibly unlikely that a culture would want to absorb 100% of a suns energy using this method, rather than losing a few shells and not having to spend the exponentially increasing cost of new shells. Only way this works is if a species has figured out how to not have to worry about the laws of physics, in which case, why are they bothering with locating it around a specific star in the first place?
