Perovskite solar cells
Perovskite solar progress now covers full modules as well as record cells. Oxford PV and Fraunhofer reported 25.6% full-area tandem modules in June 2026. A commercial advantage still needs reproducible manufacturing, durability in the field and a competitive installed cost, and a licence proves none of these.

Core thesis
Perovskite layered on silicon converts more sunlight into power than silicon alone. LONGi's 2025 interim report gives 34.85% efficiency for a research cell of this kind, certified by the US National Renewable Energy Laboratory. That is a laboratory cell. On full-size modules, Oxford PV and Fraunhofer reported 25.6% in June 2026. Efficiency is only part of the test. Commercial use depends on manufacturing yield, how long modules last outdoors, whether they hold up over their warranty period, and installed cost.
State of the art (2026)
The lab race is won and the commercial race has started. LONGi holds the NREL-certified perovskite-silicon tandem record at 34.85% (2025), with a ~35% ESTI claim still uncertified. The decisive 2025-26 shift is manufacturing: GCL opened the first gigawatt-scale perovskite tandem line in Kunshan (June 2025) at 29.51% certified module efficiency, with mass production and first shipments due through 2026; UtmoLight is running a 1GW line. Oxford PV ships ~25% tandem modules and has licensed its IP to Trinasolar (China, 2025) and First Solar (US, Feb 2026), targeting full mass production in 2027 and a 20-year lifetime by 2028. Field-stability and 25-year bankability remain the unresolved gate to utility scale.
