Single-junction perovskite solar cells (PSCs) have been one of the most promising photovoltaic technologies owing to their high-power conversion efficiencies (PCEs) ~27% and low-cost fabrication processes involved, which pay off significantly given distinct structural characteristics. Recently, inorganic hole-transport materials (HTMs) such as nickel oxide (NiOx) developed received considerable attention for use in OPVs due excellent thermal stability, materials, compatibility with scalable deposition methods. Here, we summarize recent progress on HTMs PSCs, can be divided into three categories: NiOx, copper-based compounds, emerging new alternatives. The method (sputtering, atomic layer deposition, or a solution-based technique) is important factors affecting performance stability PSCs.

We also balance benefits against key challenges advancing commercialization, namely interior defects environmental degradation.

Abstract All‐inorganic tin (Sn)‐containing perovskites have emerged as highly promising photovoltaic materials for single‐junction and tandem perovskite solar cells (PSCs), owing to their reduced toxicity, optimal narrow bandgap, superior thermal stability. Since initial exploration in 2012, significant advancements been achieved, with the highest efficiencies of devices now surpassing 17% 22%, respectively. Nevertheless, intrinsic challenges associated oxidation susceptibility Sn 2+ uncontrolled crystallization dynamics impede further development. Addressing these issues necessitates a comprehensive systematic understanding degradation mechanisms inherent all‐inorganic Sn‐containing perovskites, well development effective mitigation strategies. This review provides detailed overview research progress PSCs, particular focus on basic properties pathways both pristine mixed Sn‐Pb perovskites. Furthermore, various strategies improve efficiency stability PSCs are thoroughly discussed. Finally, existing perspectives provided improving performance eco‐friendly PSCs.

Semitransparent perovskite solar cells can provide auxiliary power in applications such as power-generating windows and smart car windows. However, conventional planar-structured devices, both the conversion efficiency (PCE) average visible light transmittance (AVT) of devices are restricted by band gap or thickness absorption layer, which hinders development application semitransparent cells. In this work, we construct a new type cell with three-dimensional (3D) mesh structure using nickel framework bottom electrode. The AVT device is controlled mesh. When narrow materials were deposited, PCE was 4.48%, 16.5%, color rendering index 98.35, bifacial coefficient reached 79%. Additionally, due to flexible nature mesh, exhibited excellent mechanical stability, maintaining 90% its initial after 1000 bending cycles at R = 10 mm. This provides idea for realizing high transmittance. It expected promote their wide fields building-integrated photovoltaics.
