HTL Resummation of the Thermodynamic Potential

open access: yes, 2000
Starting from the Phi-derivable approximation scheme at leading-loop order, the thermodynamical potential in a hot scalar theory, as well as in QED and QCD, is expressed in terms of hard thermal loop propagators. This nonperturbative approach is consistent with the leading-order perturbative results, ultraviolet finite, and, for gauge theories ...

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)

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 ...

Numerical Design and Performance Optimization of Lead‐Free CsSnGeI3 Perovskite Solar Cells Using Cu2O Hole Transport Layer via SCAPS‐1D

open access: yesEnergy Science &Engineering, EarlyView.
The optimal structure of the device FTO/ZnS/CsSnGeI3/Cu2O/Au consists of a CsSnGeI3 absorber layer and ZnS as the buffer layer, FTO as the electron transport layer, and Cu2O as the hole transport layer. For the back contact, gold is utilized. According to the current density–voltage curve, efficiency increases with thickness concurrently.
