Scientists at ITMO University and their colleagues from the St. Petersburg Academic University and University of Tor Vergata (Italy) have developed high-performance perovskite solar cells. The improvement is thanks to the use of semiconductors based on wire-like nanocrystals.

Researchers from ITMO have demonstrated a novel technique for generation of laser radiation that utilizes perovskite metasurfaces. The solution will pave the way for next-gen lasers that are less than 100 nm thick and require significantly less energy.

The new device includes a structure of single-atom semiconductors and an ultracompact nanoresonator. The switching is conducted with light, via changes in the exciton states in each of the two semiconductor layers.

A research team featuring scientists from ITMO University and the City University of New York has successfully created controllable topological states that can be selectively excited on a silicon chip.

Students of ITMO’s School of Physics and Engineering have developed a prototype of a portable keyboard that is only 3 mm thick and provides haptic feedback. The new device is compatible with PCs, smartphones, and tablets, while its production cost amounted to less than 1,000 rubles.

In spite of their many disadvantages, batteries remain one of the key components in contemporary electronics.
