High Short-Circuit Current Density via Integratingthe Perovskite and Ternary Organic Bulk Heterojunction
Abstract
We demonstrate a record short-circuit current density (28.06 mA/cm2) in a single-junction perovskite solar cell with a 1.6 eV bandgap absorber. We achieve this by integrating a ternary organic bulk heterojunction structure into a perovskite top layer to extend the photoresponse to the near-infrared region.
