Actually it does change, from what I read mainly in terms of what substance is used to capture the heat of the sunlight, which in turn has other implications downstream (for example, if you melt salt and the molten salt is used to generate steam, rather than directly generating the steam, not only does the efficieny go up but you can keep on generating power during the night as long as there’s enough heat left in the salt).

Here is paper I found about it.
