tandem module

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%.
