Heterojunction cell and module producer Meyer Burger has established a brand new collection of partnerships to analysis and develop perovskite tandem photo voltaic know-how, with a view to bringing the know-how to industrial scale.
The Switzerland-headquartered firm will accomplice with the Swiss Centre for Electronics and Microtechnology (CSEM), Helmholtz-Zentrum Berlin (HZB), Fraunhofer ISE and the College of Stuttgart to pursue industrialised perovskite manufacturing and higher effectivity in future PV modules.
Meyer Burger mentioned that the work with the brand new consortium relies on its current collaborations for the event of heterojunction cells. The corporate beforehand labored with Oxford PV on a partnership to develop perovskite-on-silicon tandem know-how, however this partnership ended abruptly in 2021 when Oxford PV pulled out of the settlement. The UK-based firm turned a service provider heterojunction/perovskite photo voltaic cell producer in 2019.
Meyer Burger additionally mentioned that, in partnership with CSEM, it has already achieved 29.6% power effectivity for a 25cm2 perovskite tandem cell, by combining silicon heterojunction cells with perovskite buildings.
“This excellent outcome demonstrates the potential of silicon perovskite tandem cells to attain excessive efficiencies. Though we nonetheless have numerous work forward of us, the industrialisation of photo voltaic cells with an effectivity of over 30% is heading in the right direction,” mentioned Christophe Ballif, director of sustainable power at CSEM.
In October, researchers claimed {that a} file of 30.1% effectivity had been achieved for four-terminal perovskite-silicon tandem PV cells. HZB claimed that it has achieved a file in extra of 31% effectivity in laboratory tandem photo voltaic cells, and that its partnership with Meyer Burger will look to deliver these outcomes to the manufacturing of business merchandise.
Marcel König, head of analysis and improvement at Meyer Burger mentioned: “With an extended custom of proprietary improvement, Meyer Burger has an in depth portfolio of processes, applied sciences and manufacturing strategies at its disposal for the potential mass manufacturing of tandem photo voltaic cells and modules in-house.”
Perovskite tandem cells undergo from excessive ranges of degradation with will increase in measurement. Analysis is ongoing throughout Europe into discovering methods to scale perovskites, such because the just lately introduced PEPPERONI consortium run by HZB and photo voltaic producer Qcells.
“The intention is for perovskite/silicon modules to fulfill the excessive requirements of reliability and longevity set by classical silicon PV know-how,” mentioned Andreas Bett, director of Fraunhofer ISE.
A latest research by researchers in Germany discovered that perovskite-on-silicon PV modules are extra environmentally advantageous throughout their lifecycle than conventional PV modules.
