Researchers have developed a novel passivation process for formamidinium lead iodide perovskite films, which reportedly resulted in solar cells with 23.69% power conversion efficiency, and modules ...

Both lead iodide (PbI2) and formamidinium iodide (FAI) benefitted from the PZ immobilization strategy, enabling the formation of “high-quality” perovskite films for the cells.

Perovskites have tunable band gaps and function well even ... By replacing methylammonium with a combination of cesium and formamidinium, replacing metal electrodes with indium tin oxide and packaging ...

Dr Briscoe has been working with perovskite solar cells, which are made of a material normally containing lead, a halide (normally iodide or bromide) and an organic molecule, such as methylammonium ...

Both scores are among the highest ever achieved with perovskite solar cells. They also found that the cells demonstrated long ...
