Highly controllable and reproducible one-step synthesis of β-NaYF₄:Er³⁺@NaYbF₄@NaYF₄ upconversion nanoparticles for Sb₂(S,Se)₃ solar cells with enhanced efficiency

Abstract

Multilayer structures of upconversion nanophosphors are widely considered as an effective and necessary strategy to achieve efficient luminescence. However, the synthesis of high-quality upconversion nanoparticles in a controllable and reproducible...

Energy harvesting and electricity production through dissolved carbon dioxide by connecting two form-stable phase change materials

“…6,7 Harnessing sunlight to generate electrical energy has been done by solar cells. 8,9 This is related to a solar photovoltaic (PV) system which can convert sunlight into usable electricity directly. 10,11 Moreover, solar energy can be utilized for solar heating and cooling applications to generate electrical energy according to the Seebeck effect.…”

Co-doped NaYF4:Yb/Er/Tm upconversion luminescent coating to enhance the efficiency of photovoltaic cells

“…18 But the synthesis of high-quality NaYF 4 :Ln 3+ with specific sizes and morphologies in a simple way is still a challenge. 19 Impurity doping has recently been recognized as having a significant influence on the crystal phase, size and luminescence properties of NaYF 4 :Ln 3+ materials with simple synthesis. 20,21 The results show that transition metal (TM n + ) ion doping can effectively utilize and regulate the luminescence efficiency of Ln 3+ ions.…”
