They found that doing so led to stronger bonds between PbI 2 and hydrogen due to the presence of the formamidinium iodide. It also led to improved uniformity as evidenced by reduced colloidal ...

We report formamidinium lead iodide perovskite n-type transistors with field-effect mobilities of up to 33 cm 2 V −1 s −1 measured in continuous bias mode." ...

A team of São Paulo-based researchers have found incorporating formamidinium cations into methylammonium-based lead iodide perovskite films increases the durability of perovskite solar cells when ...

A team led by University of Electronic Science and Technology of China (UESTC) has found that pyrrodiazole as an additive in formamidinium iodide (FAI)-based inverted perovskite solar enables ...

This is a temperature at which the stability of formamidinium iodide-based solar cells is known to be limited. Exposure for a long time means the team generated "ultra-stable" 3D perovskites.

In the paper A combined molecular dynamics and experimental study of two-step process enabling low-temperature formation of phase-pure α-FAPbI3 the authors chose to study, to this end, the two ...
