Organic–inorganic perovskite solar cells have achieved an impressive power conversion
efficiency of up to 25.6% and 24.8%, respectively, for single and multijunction tandem …

P‐type NiOx films are widely used as hole‐transport layers (HTLs) in p–i–n perovskite solar
cells (PSCs) owing to their wide bandgap, stability, and optical transmittance. Chemical bath …

Nickel oxide (NiO) is one of the promising hole‐transporting materials for perovskite solar
cells (PSCs). Despite the ongoing efforts to improve PSC performance with sol–gel NiO …

As a convenient, low-cost and up-scalable solution route, chemical bath deposition (CBD)
has exhibited impressive advantages in fabricating electron transporting materials like SnO …

Increasing energy demands, depletion of fossil fuels, and environmental issues have
impelled society to choose the pathways of renewable and clean energy, which motivated …

Recent reports have shown that nickel oxide (NiO) when adopted as a hole transport layer
(HTL) in combination with organic layers, such as PTAA or self-assembled monolayers …

Five mixing molar ratios, 1: 0.6, 1: 0.8, 1: 1.0, 1: 1.2, and 1: 1.4, of conventional nickel (II) bis
(acetylacetonate)(Ni (acac) 2) and a diethanolamine (DEA) stabilizer have been tried for …

Nickel hydroxide has been successfully employed as a precursor to the widely used,
inorganic hole transport material (HTM) nickel oxide (NiO x). However, manufacturing NiO x …

In the present work, pure TiO 2 and Fluorine doped TiO 2 (F–TiO 2) thin films were prepared
and their effect on the photovoltaic response of perovskite solar cells was investigated. Six …

The recombination of charge carriers at the interface between carrier transport layers such
as nickel oxide (NiOx) and the perovskite absorber has long been a challenge in perovskite …
