Concentrated photovoltaic thermal (CPVT) solar collectors have been gaining ever-
increasing attention from the scientific community and industrial developers due to their …

Downshifting (DS) and downconversion (DC) are processes in which a high-energy photon
is converted into one or several lower-energy photons, respectively. These processes have …

This paper describes the synthesis of Eu (III)-doped ZnB2O4 (B= Al (III) or Ga (III))
nanospinels with Eu (III) concentrations varying between 1% and 15.6%. The synthesis was …

The down-conversion or down-shifting of high-energy photons into “cold” photons—photons
with reduced energy—presents an innovative strategy for enhancing the performance of …

The goal of the present chapter is the maximum utilization of the solar spectrum of light and
minimizing various types of energy losses (thermal or photon loss) that take place during the …

Silicon nanocrystal (Si-NC) luminescent down-shifting materials for photovoltaic (PV)
applications were fabricated by ion implantation and plasma-enhanced chemical vapor …

The mismatch between solar cell response and solar spectrum is one of the biggest
challenges to achieve high efficiency in photovoltaic cells. There are a few different …

The performance effects of silicon nanocrystals (SiNC) embedded in a silicon dioxide matrix
to act as a downshifting (DS) layer mounted on the top surface of a polycrystalline Cu (In …

Conventional Cu (In, Ga) Se2 (CIGS) solar cells suffer poor response in the short-
wavelength region (280 to 520 nm) due to the parasitic absorption in the ZnO transparent …

Recently, rare-earth doped fluorescent materials have been attracting a lot of attention
because of their high quantum yield, sharp emission bandwidth, photostability, low toxicity …
