Oxford PV

Meyer Burger claims machines to produce perovskite tandem solar cells are still missing at Oxford PV’s manufacturing plant in Germany’s Brandenburg an der Havel. Despite this, Oxford PV terminated the cooperation with the turnkey machine supplier in a surprise move last week. The Swiss technology group, which now produces its own heterojunction solar cells and modules in Germany, is now considering legal action.

Perovskite tandem developer Oxford PV has completed the fit out of its 100 MW tandem cell line in Brandenburg, Germany – although the company awaits for the delivery of one perovskite deposition tool, which would complete the high efficiency cell process. Oxford PV, which in December 2020 hit a new world record cell efficiency of 29.52%, hopes to begin commercial production in early 2022.

Perovskite developer Oxford PV has set a new world record for perovskite-silicon tandem cell efficiency at 29.52%, edging out the previous record set less than a year ago by Helmholtz Zentrum Berlin. The new record has been certified by the U.S. National Renewable Energy Laboratory.

Oxford PV is currently building a manufacturing facility for its silicon perovskite tandem solar cells in Brandenburg an der Havel.

The annual EU PVSEC conference got under way virtually this morning via an online platform since the planned event in Lisbon could not go ahead due to the Covid-19 pandemic. Opening presentations revealed an air of optimism in the PV industry, amid expectations of a rapidly rising share in the energy mix, growing conversion efficiencies, advancing technology pathways and innovative solutions to the problem of integrating high levels of PV into electricity grids.

The International Energy Agency has acknowledged dramatic falls in energy investment caused by the Covid-19 crisis but said renewables, including PV, offered an attractive proposition to investors as the dust settled, given their enticing economics and short turnaround times.

Chief executive Gunter Erfurt told a German radio station a solar factory in North Rhine-Westphalia could supply high-efficiency panels for a 10 GW floating solar project on the vast Hambach open-cast coal mine.

Scientists at Australian National University have achieved a 27.7% efficiency rate for mechanically stacked perovskite-silicon tandem cells.

Solar module manufacturers should begin testing new technologies in higher-value niche markets, say scientists at the U.S. institution. For example, bringing perovskite technology directly to the mainstream market remains prohibitive in terms of initial investment but segments such as building-integrated PV or microelectronics devices may offer better routes to commercial maturity.

Scientists at the Helmholtz Zentrum Berlin have taken back the world efficiency record for a perovskite/silicon tandem solar cell, achieving 29.15% with a device measuring 1cm². The record has been confirmed by Fraunhofer ISE, and according to HZB, this means that the 30% efficiency mark is within reach.
