ISC Konstanz researchers say their new n-type tunnel back contact (TBC) solar cell features polycrystalline silicon TOPCon contacts on both polarities. The results still need to be confirmed by an independent third party.German research institute ISC Konstanz has claimed a power conversion efficiency of 24% for a TBC solar cell. The researchers said their new IBC4EU solar cell was designed in accordance with the polyZEBRA concept.
