CdTe is one of the leading materials for high-efficiency, low-cost, and thin-film solar cells. In
this work, we review the recent first-principles study of defect properties of CdTe and present …

We present a theoretical description of the response of a dynamic slab, with time-periodic
dielectric function ϵ (t), to a normally incident monochromatic plane wave of frequency ω o …

By combining the electron–phonon coupling effect and the static coupling formalism, we
calculate, through the first-principles methods, the carrier capture cross sections of the three …

Non-radiative recombination plays an important role in the performance of optoelectronic
semiconductor devices such as solar cells and light-emitting diodes. Most textbook …

Light-emitting diodes (LEDs) have become quite a high-performance device of late and are
revolutionizing the display and illumination sectors of our economy. Due to demands for …

Nonradiative carrier recombination is of both applied and fundamental interest. Here a novel
algorithm is introduced to calculate such a deep level nonradiative recombination rate using …

The optical properties of Al-rich AlGaN/AlN quantum wells are assessed by excitation-power-
dependent time-integrated (TI) and time-resolved (TR) photoluminescence (PL) …

Nonradiative carrier recombination is of both great applied and fundamental importance, but
the correct ab initio approaches to calculate it remain to be inconclusive. Here we used five …

The efficiencies of Cu 2 ZnSn Se 4 (CZTSe) solar cells with a narrower band gap at 1.0 eV
are currently higher than those of Cu 2 ZnSn S 4 (CZTS), with the optimal band gap …

Time-resolved photoluminescence and light-induced transient grating measurements of
GaN epilayers show that the photoluminescence decay can be described by two coupled …
