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. Wide–band gap perovskites could boost the efficiency of silicon solar cells by forming tandem cells, but usually the perovskite must be grown on a smoothed side of the silicon cell because the material grown on the rough light-trapping side often does not fully coat the silicon surface and its rough texture is prone to phase separation. Tandem solar cells represent an attractive technology to overcome the Shockley-Queisser limit of single-junction cells. Recently, wide-bandgap metal halide perovskites are paired with complementary bandgap photovoltaic technologies (such as silicon, CIGS, and low-bandgap perovskites) in tandem architectures, enabling a pathway to achieve industry goals of pushing power-conversion-efficiency.
