Key Points

Higher efficiency of two-terminal perovskite/Cu(In,Ga)Se2 tandem solar cells was observed with coatings.
The efficiency reached over 26%, reflecting significant improvements in solar cell performance.
The study used advanced coatings to address topographic irregularities in commercially available CIGS substrates.
These findings suggest potential enhancements in solar technology through improved tandem cell designs.

Implication

Performance of two-terminal solar cells improves with perovskite/Cu(In,Ga)Se2 tandem design, indicating efficiency potential.

Abstract

High-performance of two-terminal (2-T) perovskite/Cu(In,Ga)Se2 (PVK/CIGS) tandem solar cells (TSCs) is fundamentally limited by submicron-scale topographic irregularities inherent to commercially available CIGS substrates. We demonstrate that these features induce spatial...
