Flexible Perovskite Photovoltaic Modules and Solar Cells Based on Atomic Layer Deposited Compact Layers and UV‐Irradiated TiO₂ Scaffolds on Plastic Substrates

Flexible perovskite photovoltaic modules are demonstrated for the first time. Low-temperature processes including UV-irradiation of the mesoporous TiO2 and atomic layer deposition of the compact TiO2 helps deliver solar cells with 8.4% efficiency, good flexibility, and improved stability with respect to scaffoldless equivalents. Screen-printable scaffolds and masking/laser patterning procedures enables fabrication of 3.1%-efficient mesostructured perovskite modules on plastic substrates.
