solar cells with an efficiency of 24.7% (certified 24.4%), outperforming all types of flexible thin-film solar cell. We also report 23.5% efficiency for larger device areas of 1.05 cm2. The molecule-bridged interfaces enable significant bending durability of flexible all-perovskite tandem ...
Next, we demonstrate a bandgap tuning strategy based on A-site cations of mismatched size (dimethylammonium and cesium) to enable a 1.7eV perovskite with high, stable voltages. By combining these advances, we fabricate two-terminal all-perovskite tandem solar cells with 23.1% power conversion ...
The flexible and all-perovskite tandem solar cells devised by the researchers have a carefully studied design and composition. When their frontal cell, comprised of a perovskite film with a wide bandgap, is illuminated by the sun, it absorbshigh energy photons. Its posterior cell, on the other ...
Flexible all-perovskite tandem photovoltaics open up new opportunities for application compared to rigid devices, yet their performance lags behind. Now, researchers show that molecule-bridged interfaces mitigate charge recombination and crack formation,

In theory, this allows efficiencies of up to 45%—much higher than the 33% of single-junction cells. Alternatively, a perovskite layer can also be added to a silicon cell to create a highly efficient tandem cell. However, Fu and his team are currently focusing on all-perovskite tandem cell...
Flexible perovskite solar cells (FPSCs) have attracted enormous interest in wearable and portable electronics due to their high power-per-weight and low cost. Flexible and efficient perovskite solar cells require the development of flexible electrodes compatible with the optoelectronic properties of perovs...
