Enabling Flexible All-Perovskite Tandem Solar Cells
Open accessAbstract
Summary Multijunction all-perovskite solar cells offer a route toward efficiencies of III-V materials at low cost by combining the advantages of low thermalization loss in multijunction architectures with the beneficial properties of perovskites—namely, low processing cost, high-throughput fabrication, and compatibility with flexible substrates. However, there are two main challenges for enabling high-efficiency tandems: (1) design of a recombination layer to efficiently combine two perovskite subcells while also preventing bottom cell damage during top cell processing and (2) achieving high open-circuit voltage of the wide-gap subcell. Herein, we overcome both of these challenges. First, we demonstrate a nucleation layer consisting of an ultra-thin polymer with nucleophilic hydroxyl and amine functional groups for nucleating a conformal, low-conductivity aluminum zinc oxide layer by atomic layer deposition (ALD). This method enables ALD-grown recombination layers that reduce shunting as well as solvent degradation from solution processing on top of existing perovskite active layers. Next, we demonstrate a band-gap tuning strategy based on A-site cations of mismatched size (dimethylammonium and cesium) to enable a 1.7 eV perovskite with high, stable voltages. By combining these advances, we fabricate two-terminal all-perovskite tandem solar cells with 23.1% power conversion efficiency on rigid substrates and 21.3% on flexible plastic substrates.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
