wow the pop science on this is hardcore. Yes it is cool they made a dual junction cell with silicon and perovskite, but triple and quad junction cells have been doing better than pure silicon cell for a long time.

Multi-junction silicon cells are very unlikely to ever be commercially viable for the mass market. The advantage of silicon-perovskite tandem cells is that it's only a small production price increase over current solar cells.
