We report size-dependent exciton formation dynamics within colloidal silicon quantum dots
(Si QDs) using time-resolved terahertz (THz) spectroscopy measurements. THz …

A lot of research has been lately conducted on perovskites, which show promising
properties for many applications, ranging from optoelectronics to photovoltaics. Recently, a …

Colloidal silicon nanocrystals (SiNCs) exhibit promise for applications in optoelectronics and
bionanotechnology, attributed to their distinct surface-tunable photoluminescence (PL) and …

We use the Boltzmann transport equation (BE) to study time evolution of a photoexcited
state, including phonon-mediated exciton relaxation, multiple exciton generation (MEG), and …

We use a Boltzmann transport equation (BE) to study time evolution of a photo-excited state
in a nanoparticle including phonon-mediated exciton relaxation and the multiple exciton …

Efficient multiple exciton generation (MEG) in chiral single-wall carbon nanotubes
(SWCNTs) is present within the solar spectrum range as shown by the many-body …

Singlet fission (SF) process, where a singlet exciton decays into a pair of spin one exciton
states which are in the total spin singlet state, is one of the possible channels for multiple …

A new mechanism of the energy relaxation of hot charge carriers in silicon nanocrystals
embedded in the SiO 2 matrix is suggested. Effective energy exchange between “hot” …

Multiple exciton generation (MEG) in nanometer-sized hydrogen-passivated silicon
nanowires (NWs), and quasi two-dimensional nanofilms depends strongly on the degree of …

The most important limitation for the efficiency of photovoltaic energy conversion is related to
the mismatch between the broadband character of the solar radiation and the spectral …
