No laboratory value, no theoretical maximum: In Brandenburg, Germany, the production of high-performance solar modules using the tandem process begins.https://www.notebookcheck.net/Solar-cell-with-27-percent-efficiency-thanks-to-perovskite-layer-goes-into-production.850750.0.html
Yup - if the price is right. Basically, they've slapped a perovskite layer over the silicon layer. For an increase in yield of 30%. This upgrade will likely cost more than 30% price increase over a silicon cell.
Sign me up. I'll pay 50% more for these. Probably pares well to a ground based array that tracks the sun.

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
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.
