Researchers developed a new technique to fabricate perovskite absorbing layers for multijunction solar cells, achieving a record power conversion efficiency of 26.4%. This technique involves a double-sided sandwich evaporation process that allows for precise control over the halide ratio and B-site doping of the perovskite absorber layers. The resulting triple-junction tandem solar cell exhibits significantly higher efficiency than previous designs.
How Setfos was used.
theoretical insight for the optimal perovskite thickness was gained using Setfos by taking into account the reflection of the bottom cell, so the thickness of the top layers could be reduced.
