## Description

- description: 'Wide bandgap perovskite devices are promising as the top cell of silicon-perovskite
    tandem devices to boost the efficiency beyond the Shockley-Queisser limit. Here,
    we tailor the performance parameters of wide bandgap (WB) (MAPb(I1-xBrx)3) perovskite
    based device with long chain alkyl substituted fullerene derivatives as an electron
    transport layer (ETL). The device with C60-fused N-methylpyrrolidine-meta-dodecyl
    phenyl (C60MC12) demonstrates an enhanced efficiency of 16.74 % with the record
    open circuit voltage (VOC) of 1.24 V; an increase by 70 mV with concomitant VOC
    deficit reduction to 0.47 V. This is achieved by mitigating the recombination
    loss through the use of highly crystalline C60MC12 film compared to amorphous
    PCBM layer. The device analysis reveals the soothing of the defect '
