Sao Paulo, Brazil (SPX) Mar 15, 2021 Quantum dots are manmade nanoparticles of semiconducting material comprising only a few thousand atoms. Because of the small number of atoms, a quantum dot’s properties lie between those of single atoms or molecules and bulk material with a huge number of atoms. By changing the nanoparticles’ size and […]

A new modifier increases the efficiency of perovskite solar cells
www.solarenergyconnect.com

Moscow, Russia (SPX) Feb 12, 2021 The research team of NUST MISIS has presented an improved structure of perovskite solar cells. Scientists have modified perovskite-based solar cells using MXenes – thin two-dimensional titanium carbides with high electrical conductivity. The MXenes-based modified cells showed superior performance, with power conversion efficiency exceeding 19% (the reference demonstrated 17%) […]
