Periodic nanostructures, a group of nanomaterials consisting of single or multiple nano
units/components periodically arranged into ordered patterns (eg, vertical and lateral …

In this review, the author highlights the history, importance and emerging applications of up-
conversion (UC) assisted solar cells. An attempt has been made to elucidate the …

Abstract Development of high-efficiency solar cells is one of the attractive challenges in
renewable energy technologies. Photon up-conversion can reduce the transmission loss …

We studied the dynamics of electrons generated by two-step photoexcitation in an
intermediate-band solar cell (IBSC) comprising InAs/GaAs/Al0. 3Ga0. 7As dot-in-well …

We applied hot-carrier extraction to solar cells and photocatalysts used for artificial
photosynthesis including water splitting and CO 2 reduction, and elucidated the differences …

To improve the superlattice (SL) solar cell performance, we carried out an accurate
estimation of transition energies and miniband widths and focused on understanding of the …

Intrinsic losses, including below-band gap, thermalization, mismatch angle, Carnot, and
emission, are investigated in a structure of quantum dot intermediate band solar cells (QD …
