Read our privacy policy Researchers from Germany have set a new world record in solar cell efficiency using the so-called ‘miracle material’ perovskite. The record they set of 24 per cent efficiency was a 4 per cent improvement on the previous tandem cell record, though still falls short of the silicon solar cell record of 26.7 per cent. The new materials, however, hold far greater potential for improved efficiency in the future, whereas silicon solar cells are now considered “as good as it gets” with an intrinsic limit of around 29 per cent. “To solve this problem, the group in Wuppertal developed a so-called interconnect that couples the organic sub-cell and the perovskite sub-cell electronically and optically.” A study detailing the breakthrough, titled ‘Perovskite/ organic tandem solar cells with indium oxide interconnect’, was published in the journal Nature on Wednesday.
