A Chinese research team has fabricated an all-perovskite solar cell with a 3D/3D double-layer perovskite heterostructure that reportedly ensures improved charge extraction. The device achieved an open-circuit voltage of 2.112 V, a short-circuit current of 6.5 mA cm-2, and a remarkable fill factor of 81.9%.Researchers at the Nanjing University in China have fabricated an all-perovskite tandem solar cell that reportedly shows lower interfacial non-radiative recombination and improved charge extraction. All-perovskite tandem cells - where two different perovskite cells are stacked on top of each ...Den vollständigen Artikel lesen ...
