tandem cells

The Intersolar Europe 2024 trade show closed its doors for another year on Friday (21st June). Ahead of further coverage and interviews from the conference, this piece will collate a few of the key takeaways that we saw on the ground at the show last week.

JinkoSolar has developed a new tunnel oxide passivated contact (TOPCon) perovskite tandem cell, with a power conversion efficiency of 33.24%.

Khajeh Nasir Toosi University of Technology reserachers have developed ‘half-tandem’ solar cells with a power conversion efficiency of 27.63%.

LONGi has developed a crystalline silicon-perovskite tandem solar cell with a power conversion efficiency of 33.9%, the highest on record.

Upstream US-based solar manufacturer CubicPV might feasibly be the place at which tandem perovskite PV products are successfully made durable enough for commercial use; two recent announcements have come out of the company that speak to the potential of its tandem development route.

The National University of Singapore and REC Solar have launched a US$57.4 million (S$77 million) solar cell research initiative.

Enel Green Power’s Sicilian subsidiary 3Sun has developed a 9cm squared silicon-perovskite tandem PV cell in partnership with the French national institute of solar energy (INES) and the CEA, a French government-funded research institution.

Fraunhofer ISE has set up a testing apparatus for perovskite solar PV cells and modules, aiming to establish a reliable efficiency standard for the technology.

Italian PV manufacturer FuturaSun has acquired a research and development startup, Solertix, which focuses on perovskite cell technology research.

Perovskite solar cell researchers Oxford PV have claimed a new world record for commercial solar cell efficiency, recording a 28.6% efficiency on a 258.15 cm2 perovskite tandem cell independently certified by Fraunhofer ISE.
