A Co‐Self‐Assembled Monolayer With Enhanced Coverage and Defect Passivation for Efficient Inverted Perovskite Solar Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved a co‐self‐assembled monolayer (Co‐SAM) with more uniform coverage on nickel oxide substrates and enhanced passivation of buried interfaces by incorporating 4PABCz into Me‐4PACz. Perovskite solar cells fabricated with this Co‐SAM achieved an efficiency of 26.33% and exhibited enhanced stability. The combination of nickel oxide (NiOx)

Erhält die HTL von Mikroalgen durch die Elektroporation neue Impulse?

open access: yes, 2019
Mikroalgen sind in den Fokus der Forschunggerückt, weil sie auf Grund ihrer hohen Fotosyntheseleistung gute Wachstumsraten haben und damit ein hohes spezifisches Flächennutzungspotential aufweisen.

Managing Crystallization in Tin‐Lead Perovskite Solar Cells via Differential Chelating Coordination

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A chelation‐mediated crystallization strategy is developed for Sn–Pb perovskites using 1,10‐phenanthroline. Stronger coordination with Sn than Pb helps reconcile their mismatched crystallization behavior, leading to improved crystalline quality, fewer defects, and reduced oxidation.

Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

open access: yesFlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.
