Tandem solar cells : "how to get higher efficiency" in RTS television
The Swiss TV channel RTS (in French) broadcasted a report on the world record tandem device fabricated at PV-Lab using silicon as bottom cell and perovskite as top cell.
The news magazine “Le 12h45” of the Swiss TV channel RTS presented our innovative silicon/perovskite tandem cells as a low-cost alternative to III-V materials on June 4th. The device architecture is a promising candidate to beat the 30% efficiency benchmark. The video can be found here (in French).
