Graphene‐Engineered Rear Interfaces Enable Efficient Flexible CZTSSe Solar Cells on Metal Foils

Yixiong Ji, Wentong Yang, Yan Di, Wei Luo et autres

ABSTRACT Flexible kesterite (S,Se) (CZTSSe) solar cells on metal foils are attractive for lightweight and conformable photovoltaic applications, yet their efficiencies remain significantly lower than those of rigid devices due to severe foil‐induced rear‐interface losses during high‐temperature chalcogenization. These effects include uncontrolled …

Sulfate-reducing bacteria in acid mine drainage: ecological constraints, microbial networks, and functional persistence

Rui Xiao, Jiaoyang Liu, Cunzeng Li, Yang Peng et autres

Sulfate-reducing bacteria (SRB) are key functional microorganisms in the bioremediation of acid mine drainage (AMD), simultaneously removing sulfate, generating alkalinity, and precipitating metal sulfides via dissimilatory sulfate reduction. AMD is typically characterized by low pH, high sulfate and metal concentrations, and limited …

Enhancing Phonon Group Velocities and Interfacial Heat Conduction for Efficient and Stable Perovskite Solar Cells

Xing Wu, Yuehua Chen, Yang Shen, Er-Wei Du et autres

The inherently low thermal conductivity of conventional hole-transport layers (HTLs) in inverted perovskite solar cells (PSCs) introduces a substantial discrepancy in interlayer heat-transfer dynamics, leading to detrimental heat accumulation and nonradiative recombination. Herein, we develop a spinel-type semiconductor of CuBi2O4, and integrate …

Molecular‐Extrusion‐Driven Halogen Homogenization for Efficient Perovskite‐Silicon Tandem Solar Cells

Yu Chen, Yang Peng, Chuan Luo, Yang Shen et autres

ABSTRACT Phase segregation is an inevitable phenomenon in wide‐bandgap perovskites, triggering nonradiative recombination and degrading device performance. Herein, we propose a molecular‐extrusion‐driven passivation strategy by introducing bromomethyl‐triphenylphosphonium bromide (TPB‐Br) into perovskite precursors to achieve halogen homogenization. This approach simultaneously passivates bulk and …
