Inverted perovskite solar cell with 21.1% efficiency and high moisture resistance
Australian scientists have built a perovskite solar cell based on 2D and 3D salts. By adding a fluorinated lead salt in the processing solution – normally used to form 3D methylammonium lead iodide – they were able to achieve a 21.1% efficiency, an open-circuit voltage of 1.12 V, a short-circuit current of 22.4 mA/cm2, and a fill factor of 84%.
The scientists at the University of Queensland have fabricated a solar cell based on a mixture of 2D and 3D salts. They claim that the cell is more moisture-resistant and durable than “conventional” perovskite cells based on 3D materials alone and used CMM for characterising their materials.
