Germany's Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) said this week that its new PVT solar module PX-1 from German manufacturer Sunmaxx PVT has an overall efficiency of 80%.
The module measures 1,750 mm x 1,140 mm x 38 mm and features 108 PERC half-cells in the M10 format. The electrical output is 400 W, which corresponds to an electrical efficiency of about 20%.
The new product has also a thermal output of 1,200 W, which corresponds to a thermal collector efficiency EtaO of 60%. Fraunhofer ISE measured this value under maximum power point (MPP) conditions in full sunlight, at a module temperature of 25 C, and at a wind speed of 0 meters per second.
Fraunhofer ISE has conducted additional tests on real operating scenarios on outdoor and indoor test stands. The measurements showed that the module heats up to a maximum temperature of 30 C in full sunlight. Conventional PV modules reach temperatures of up to 80 C, which reduces their efficiency.

If that works out, it will be really impressive.
My main worry would be getting them installed as you will need a roofer, an electrician and a plumber to do the job.
Would be brilliant for new builds, however.
Nice how they can keep the PV cell cool as well.
It says the thermal output is 1200 Watts, which at first seems to mean that there is a water cooled panel underneath the PV panel, but it doesn’t explicitly say that. 80% efficiency is very high so that rules out that it’s a thermoelectric panel, which is what I at first thought they meant. I think it needs clarification.
Imagine 100% efficiency with the universe. Compliance is everything!
Impossible.
