Application

Formamidinium bromide is commonly used as a precursor for the fabrication of perovskite absorber layers in perovskite solar cells. It can be combined with other components, such as lead halides and organic cations, to form the perovskite structure. FABr helps improve the optoelectronic properties and stability of the perovskite layer.
Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors with extremely low water contents are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.

Perovskite Solar Cells

Dr. Perini and Professor Correa-Baena discuss the latest research and effort to obtain higher performance and stability of perovskite materials.

Solar Cells: Towards Printable and Flexible Solar Technologies

To achieve net-zero emissions by 2050, renewable power contributions must triple. Photovoltaic stations provide vital utility power, achieved primarily through third- and fourth-generation technology. Promising trends include recycling and revolutionary, ultra-lightweight, flexible, and printable solar cells.

Ultra-High Efficiency Perovskite-Perovskite Tandem Solar Cells

Next generation solar cells have the potential to achieve conversion efficiencies beyond the Shockley-Queisser (S-Q) limit while also significantly lowering production costs.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
