Kind of- for skyscrapers especially, glare reduction, excess light mitigation and UV removal are important functions that normally lead to window tinting and indoor window covers anyway. If you can get those effects cheaply enough and in the right proportions, then PV windows could be a viable technology.

They will always be worse than rooftop PV- I wouldn't be surprised if a skyscraper's windows produced less electricity than its rooftop array, due as well to the poor window positioning for PV- but if they're filling multiple functions then they might be worthwhile. It would be like complaining about windows for lighting when LEDs work just as well.
