Oxford PV has set a brand new world document effectivity for a big perovskite-silicon tandem cell, at 28.6%, a measurement confirmed by Germany’s Fraunhofer ISE. The general document for perovskite-silicon tandem cell effectivity is presently held by Stefaan De Wolf’s group on the King Abdullah College of Science and Expertise in Saudi Arabia, which achieved 33.2% in a tool measuring 1cm².

Translating excessive effectivity to bigger system sizes, made utilizing industry-compatible methods is a crucial step within the commercialization of this expertise. “Our newest effectivity achievement of 28.6% is greater than 1.5% above our document set final yr and exceeds our personal roadmap plan of 1% annual enhance,” mentioned Chris Case , Chief Expertise Officer, Oxford PV.

Oxford PV, based in 2010 as a derivative of Oxford College, produces the cell on its built-in manufacturing line in Brandenburg an der Havel, Germany, the identical line the place the 27% effectivity units are made, mentioned the corporate in an announcement.

In response to David Ward, Chief Government Officer, Oxford PV, the milestone demonstrates the corporate’s expertise and expertise however commercialization efforts are ongoing. “Whereas we proceed to evolve our perovskite-on-silicon expertise into small research-sized photo voltaic cells, most of our focus is on enhancing our commercial-sized cells for the market , ramping up manufacturing, and dealing with our photo voltaic module companions to arrange them for meeting into photo voltaic panels,” mentioned Ward. “Our workforce has made glorious progress in time for 2023 and our new photo voltaic cells are nearly within the palms of our module manufacturing clients.”
