Abstract

Two advances that address the main challenges of all-perovskite two-terminal tandem solar cell fabrication are reported. First, a nucleation layer is used to enable high-quality atomic layer deposition-based recombination layers that reduce electronic losses. Second, cation tuning is used for wide-band-gap perovskite solar cells that produce high, stable voltages. Combining these advances allows us to fabricate tandem perovskite solar cells on both rigid and flexible plastic substrates that have high efficiency and promising stability.
