2D Perovskites

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%.

Another route to high performance perovskites

Scientists at Pennsylvania State University have developed a new class of perovskite materials, which they say exhibits unique properties that could have several implications for the development of perovskite solar cells, as well as other electronic applications.
