Sodium Induced Beneficial Effects in Wide Bandgap Cu(In,Ga)S2 Solar Cell With 15.7% Efficiency

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Wide bandgap Cu(In,Ga)S2 absorbers grown on soda‐lime glass (SLG) were optimized by introducing additional sodium (Na) via in situ NaF co‐evaporation. Optimal Na incorporation enhanced crystallinity, minimized Ga fluctuations across the depth, suppressed bulk defects, and reduced non‐radiative losses.

Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...

High‐Mobility and Low Carrier Concentration Transparent Conducting Oxide Rear Contact for Bifacial CIGS Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study investigates high‐mobility, low carrier concentration (CC) transparent conducting oxides (TCOs) as back contacts in bifacial Cu (In, Ga)Se2 (CIGS) solar cells. These TCOs enhance rear‐side light absorption in CIGS and external quantum efficiency, improving overall performance by offering high transparency, low reflectance, and maintaining ...

Quantification of Alkali‐Fluoride Nanoparticle Dissolution in Aqueous Media as a Function of Crystallinity and Surface Modification

open access: yesParticle &Particle Systems Characterization, EarlyView.
Fluoride release kinetics from uncoated and coated β−NaYF4$\ubeta-{\rm NaYF}_4$ and LiYF4${\rm LiYF}_4$ in aqueous solutions are quantified using an ion‐selective electrode coupled to a dialysis compartment. TEM/DLS/ICP‐OES and speciation‐aware modeling complement the fluoride release results.
