Chemists Improve the Stability of Perovskite Solar Cells Using Passivation Method

A group of chemists from Kaunas University of Technology (KTU), Lithuania synthesised materials that were used for constructing a record-breaking perovskite solar module, with an efficiency of 21.4 per cent. This was achieved through the passivation of the active solar cell layer, which increases the efficiency of the cell and significantly improves its stability.

Experimental Realization of Atom-Optically Synthetic Gauge Field for a Noninteracting Bose Gas

Gauge fields describe the basic interactions between charged particles and are responsible for various emergent topological phases of matter. This concept recently has been further generalized to charge neutral systems by engineering an analog Hamiltonian that governs the effective dynamics of neutral particles subject to magnetic fields.

Generating Ultrashort THz Waveforms from Shifting Electrons in Asymmetric Quantum Wells

A time-dependent electric current emits an electromagnetic wave, a basic physical effect exploited in telecom antennas. Transferring this mechanism to the ultrashort length and time scales of the quantum world allows for generating intense picosecond terahertz (THz) pulses in asymmetric semiconductor quantum structures.
