tandem module

Fraunhofer ISE has increased the performance of its III-V germanium solar module from 34.2% to 34.4% using shingle-matrix technology.

Solar manufacturer Trinasolar has reached a record peak power output of 907W and a full-area efficiency of 29.2% for a perovskite/crystalline silicon tandem module.

Researchers at Germany’s Fraunhofer Institute for Solar Energy have claimed two new record efficiencies in tandem PV modules.

The South Korean Ministry of Economy and Finance has unveiled a plan to invest KRW33.6 billion (US$22.9 million) in research and development (R&D) by 2026 in solar tandem cell and module technology.

Chinese solar manufacturer Trinasolar has achieved a 30.6% large-area perovskite-silicon tandem module efficiency.

Qcells claims its perovskite/silicon tandem technology has moved a step closer to commercialisation after passing several reliability tests.

Will Norman asks if mass-scale deployment of perovskite technology is now imminent and whether it could unseat crystalline silicon as the dominant solar technology.

The report said that tandem modules need a minimum efficiency of 25% to be competitive with other solar technologies on price.

The modules themselves comprise 72 of Oxford PV’s perovskite-on-silicon cells with a conversion efficiency of 24.5%.
