By adapting the formulation and synthesis of the perovskite and the cell design and encapsulation optimization, Oxford PV succeeded in mitigating stability-related deficits and aims at providing future buyers of their modules with the industry-standard 25 year performance guarantee

The difference here is in the efficiency of the system.
And that this is an aquaponics system, which includes growing both fish and vegetables.

After more than two years of testing, Prof. Gross's system demonstrated 1.6 times higher plant areal productivity, 2.1 times lower water usage and 16% less energy consumption per kilogram of feed than conventional systems. His calculations suggest that upscaling to about one ton of fish will allow operation of the system with no need for external energy, less than 1% water exchange, negligible waste production as well as significant carbon sequestration.

I'm not sure what challenges wave power faces that tidal doesn't, but the Rance tidal power station in France has been operating since 1966.

CorPower Ocean announces wave energy breakthrough in Portuguese waters from March.

Edit: There's also Eco Wave Power Commences Sending of Clean Electricity to the Israeli National Electrical Grid from January.

Edit2: There's the 254MW Sihwa tidal power station

Tidal power plants aren't a new technology though, so I'm guessing you meant wave power.

From the article:

Oxford PV, a UK company spun out of Oxford University Physics in 2010 by Snaith to commercialize perovskite photovoltaics, recently started large-scale manufacturing of perovskite photovoltaics at its factory in Brandenburg-an-der-Havel, near Berlin, Germany. It’s the world’s first volume manufacturing line for “perovskite-on-silicon” tandem solar cells.

It might not be as thin as before, but is several microns of thickness not thin?
It was nice if they gave more details about exactly how thick it is at 27% efficiency though.
I'll look around to see if I can find more information about it.

Edit: And by the way, I'm actually not aware of any 27% solar panels currently in production.
Other than the ones Ofxord PV has recently begun manufacturing (established by the same Prof. leading this research).

One of the main advantages here is that this can be applied to almost any surface because of how thin it is.

From the article:

We can envisage perovskite coatings being applied to broader types of surfaces to generate cheap solar power, such as the roofs of cars and buildings and even the backs of mobile phones. If more solar energy can be generated in this way, we can foresee less need in the longer term to use silicon panels or build more and more solar farms.

Concrete is also used in buildings and other facilities like pumped storage hydropower.

Of silicon panels.
In the lab, mixing silicon and perovskites has already achieved 34%.

It's more about the use of perovskite (while retaining durability), which should lower the cost of the panels.
The efficiency improvement is a bonus.
