Application

Methanamine hydriodide is an important precursor for the preparation of perovskite photoactive layers for solar energy conversion.
Methylammonium iodide (MAI) is extensively used as a precursor material for the fabrication of perovskite solar cells. These solar cells offer high conversion efficiencies.
Methylammonium iodide can be used as a precursor in combination with lead iodide to change the morphology of the resulting perovskite materials. Perovskite materials can further be utilized in the fabrication of alternative energy devices such as light emitting diodes (LEDs), and perovskite solar cells (PSCs).

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.

A brief tutorial on alternative energy materials for advanced batteries and fuel cells, as well as high-purity inorganics, conducting polymers, and electrolytes.

The past several decades have seen major advancements in the synthesis of metal nanomaterials. Most recently, controlled synthesis has become versatile enough to regulate the exact number of atoms and ligands of very small metal nanoparticles, referred to as “clusters”.

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