Key Points

The study aims to enhance the performance of wide-bandgap perovskite solar cells by addressing phase separation issues through material modification.
Introduced benzylammonium thiocyanate (BnASCN) interlayer at the buried interface of perovskites.
Evaluated effects on interfacial contact and halide distribution through crystallinity improvements.
Confirmed performance gains through power conversion efficiency measurements under controlled illumination.
Achieved maximum power conversion efficiency of 22.5% for the BnASCN-modified device.
The modified device retained 90% of its original efficiency after 150 hours of continuous illumination.
Tandem cells incorporating optimized wide-bandgap devices reached a power conversion efficiency of 30.9%.
