Dutch-German consortium to bring 2T perovskite/silicon tandem PV to market – pv magazine International


The consortium mentioned it goals to develop a simplified methodology and finest practices for the manufacturing of 2T perovskite-silicon tandem photo voltaic merchandise. The modules will need to have a bifacial design, glass-glass encapsulation, and an influence output of greater than 300 W/m2.

A Dutch-German consortium led by the Netherlands Group for Utilized Scientific Analysis (TNO) goals to deliver to market a two-terminal (2T) perovskite-silicon tandem photo voltaic cell expertise within the body of a four-year analysis mission referred to as FIT4Market.

“By means of our work we wish to outline a simplified methodology to supply 2T perovskite-silicon tandem photo voltaic merchandise,” mentioned TNO Researcher Gianluca Coletti pv journal. “The monolithic tandem cell expertise we’re growing makes use of industrial PERC crystalline silicon cells with a planar entrance aspect, avoiding the complexity of coping with silicon floor texture.

The module has a bifacial design and glass by glass encapsulation, which the consortium says is nice for shielding the perovskite cells in opposition to moisture. The brand new product can have an influence output of greater than 300 W/m2, in comparison with about 200 W/m2 of typical PERC panels.

The consortium, which additionally consists of South Korea-based photo voltaic panel producer Qcells, initially sought to develop finest works for making the proposed module expertise. “We wish to improvement of tandem modules with a aggressive power price degree and industry-leading reliability and efficiency,” mentioned Jorg Muller, head of the cell Qcells R&D. “Qcells will present its silicon cell experience to the mission, along with our Benelux group taking a look at field-testing to measure real-world power efficiency and yield.”

Different members of the consortium are Dutch manufacturing gear producer Levitech NL, Netherlands-based PV gear manufacturing supplier MIT Thermal Options NL, machine producer Tempress, and Dutch provider of extrudable tie-layer resins Yparex NL.

TNO is at the moment growing a four-junction (4T) semi-transparent perovskite-silicon tandem photo voltaic cell in collaboration with the Solliance consortium together with Delft College of Know-how, the Eindhoven College of Know-how, and Belgian analysis institute Imec. This gadget achieved in September a 30.1% energy conversion effectivity.

Q Cells and German analysis institute Helmholtz-Zentrum Berlin (HZB) introduced in March that that they had achieved an effectivity of 28.7% for a two-terminal perovskite-silicon tandem photo voltaic cell.

The gadget is predicated on a silicon backside cell that depends on Hanwha Q Cells’ monocrystalline Q.antum half-cell expertise and a perovskite-based high cell.
