Agree. Obviously a few orders of magnitude in cost reduction would be required... but this seem like it could have interesting potential for energy generation in high-rise buildings, which currently have near-zero solar footprint. With that said, the lack of any mention regarding efficiency makes this part of the press release seem like a bit of smoke and, erm, mirrors.
