German analysis institute ISC Konstanz has claimed an influence conversion effectivity of 24% for a TBC photo voltaic cell. The researchers mentioned their new IBC4EU photo voltaic cell was designed in accordance with the polyZEBRA idea.
“The polyZEBRA idea is an n-type tunnel again contact (TBC) photo voltaic cell that includes polycrystalline silicon TOPCon contacts on each polarities,” ISC Konstanz researcher Jonathan Linke instructed pv journal. “The complete course of is suitable with industrially established instruments, specifically the patterning of the IBC construction is finished by laser processes and the metallization by screen-printing. The method is suitable with copper display screen printing.”
In keeping with the researchers, the imply effectivity of the cell in a batch of 16 cells was 23.7% effectivity. These outcomes have thus far not been confirmed by an impartial third-party entity.
The earlier most effectivity of the machine was 23.4%.
“Our purpose is to succeed in quickly an effectivity of 25% and an open-circuit voltage of 735 mV,” mentioned Radovan Kopecek, the co-founder and director of ISC Konstanz. “We’re working with FuturaSun on industrialization.”
In a current interview with pv journal, Kopecek mentioned that interdigitated again contact (IBC) cell tech may account for half of the worldwide marketplace for photo voltaic modules by 2030. He says IBC will begin to dominate as soon as TopCON and HJT get caught at sure effectivity limits, and he believes that TOPCon would be the first to fall.
