Alfa Chemistry Materials launches new line of perovskite materials

Alfa Chemistry Materials recently announced the launch of a comprehensive line of perovskite materials

"It is no exaggeration to say that the introduction of perovskite materials innovates various fields of optoelectronics, including photovoltaic solar cells, photodetectors, light-emitting devices, and many more,” says one of the senior scientists from Alfa Chemistry Materials. “Perovskites can be obtained from a wide range of materials and can be prepared with different methods, including the traditional high-temperature solid state method, sol-gel method, hydrothermal synthesis method, high energy ball milling method and precipitation method. Besides, other methods like vapor deposition method, supercritical drying method, microemulsion method and self-propagating high-temperature combustion synthesis method could also be used.”

New ‘self-driving’ lab developed to advance the understanding of metal halide perovskites

Researchers from North Carolina State University and the University at Buffalo have developed a ‘self-driving lab’ that uses artificial intelligence (AI) and fluidic systems to advance the understanding of metal halide perovskite (MHP) nanocrystals. This self-driving lab can also be used to investigate other semiconductor and metallic nanomaterials.

“We’ve created a self-driving laboratory that can be used to advance both fundamental nanoscience and applied engineering,” says Milad Abolhasani, corresponding author of a paper on the work and an associate professor of chemical and bimolecular engineering at NC State.

Israeli researchers develop self-healing perovskite nanocrystals

A team from Israel's Technion Institute of Technology has announced the development of self-healing perovskite nanocrystals.

Having to frequently replace electronics due to malfunctioning of materials is unavoidable today, since every device suffers from degradation as a result of defects that accumulate during use over time. This generates, in addition to customer frustration and costs, a heavy environmental footprint.

Researchers synthesize a previously theoretical nitride perovskite

Scientists at the National Renewable Energy Laboratory (NREL) have experimentally synthesized a nitride perovskite material that previously only existed in theory and measured its properties in collaboration with researchers at the Colorado School of Mines.

The new material could theoretically be used for microelectromechanical devices such as the ones used in telecommunications and other areas. Nitride perovskites have been computationally predicted to be stable, but not many have been synthesized, and their experimental properties remain largely unknown, the researchers explained in their new article.

Researchers design new method for additive-free, low-temperature production of stable α-FAPbI3 perovskite

Researchers from Queen Mary University of London, in collaboration with an international team of scientists, developed a new process for creating FAPbI3.

One of the challenges with making FAPbI3 is that the high temperatures (150°C) used can cause the crystals within the material to ‘stretch’, making them strained, which favors the yellow phase that isn’t suitable for solar cells. While previous reports have used small amounts of additional chemicals/additives to help form FAPbI3 under these conditions, it can be very hard to control the uniformity and amounts of these additives when making solar cells at a very large scale, and the long-term impact of including them is not yet known.
