It might be useful for semi-disposable applications. No one wants them on the roof only lasting for a year or so. If the top cell degrades, the efficiency would be significanly lower than the Si cell alone.

Maybe in the early days, but the cost of doing it should be fairly cheap. And even the 30% extra cost may be worth it considering you get energy during lower light conditions. Like for example, evenings when electricity is more expensive or during cloudy/rainy days

Sign me up.  I'll pay 50% more for these.  Probably pares well to a ground based array that tracks the sun.

No laboratory value, no theoretical maximum: In Brandenburg, Germany, the production of high-performance solar modules using the tandem process begins.
