The interface between NiO and perovskite in inverted perovskite solar cells (PSCs) is a major factor that can limit device performance due to defects and inappropriate redox reactions, which cause nonradiative recombination and decrease in open-circuit voltage (VOC). In the present study, a novel approach is used for the first time, where an amino acid (glycine (Gly), alanine (Ala), and aminobutyric acid (ABA))-complexed NiO are used as interface modifiers to eliminate defect sites and hydroxyl groups from the surface of NiO. The Ala-complexed NiO suppresses interfacial non-radiative recombination, improves the perovskite layer quality and better energy band alignment with the perovskite, resulting in improved charge transfer and reduced recombination.

For p-i-n perovskite solar cells (PSCs), nickel oxide (NiO) hole transport layers (HTLs) are the preferred interfacial layer due to their low cost, high mobility, high transmittance, and stability. However, the redox reaction between the Ni and hydroxyl groups in the NiO and perovskite layer leads to oxidized CHNH and reacts with PbI in the perovskite, resulting in a large number of non-radiative recombination sites. Among various transition metals, an ultra-thin zinc nitride (ZnN) layer on the NiO surface is chosen to prevent these redox reactions and interfacial issues using a simple solution process at low temperatures.

In the post-genomic era, phylogenomics is a powerful and routinely-used tool to discover evolutionary relationships between microorganisms. Inferring phylogenomic trees by concatenating core gene sequences into a supermatrix is the standard method. The previously released up-to-date bacterial core gene (UBCG) tool provides a pipeline to infer phylogenomic trees using single-copy core genes for the Bacteria domain.

Perovskite solar cells (PSCs) emerged as potential photovoltaic energy-generating devices developing in recent years because of their excellent photovoltaic properties and ease of processing. However, PSCs are still reporting efficiencies much lower than their theoretical limits owing to various losses caused by the charge transport layer and the perovskite. In this regard, herein, an interface engineering strategy using functional molecules and chemical bridges was applied to reduce the loss of the heterojunction electron transport layer.

  • - Perovskite solar cells (PSCs) are quickly improving and are nearly as effective as traditional silicon solar cells, with a special focus on their use for semi-transparent applications.
  • - Semi-transparent PSCs (ST-PSCs) have unique properties that make them suitable for tandem solar cells and building-integrated photovoltaics, but achieving a balance between light transmittance and efficiency poses challenges.
  • - Current research is exploring innovative solutions such as tuning the band-gap, enhancing charge transport layers, and developing microstructured designs to optimize ST-PSCs, while also addressing their future potential and ongoing challenges.

The dinoflagellate family Suessiaceae comprises cosmopolitan species distributed across polar and tropical waters in both marine and freshwater ecosystems, encompassing free-living forms, symbionts, and parasites. Recently, species diversity within the family has rapidly expanded, now including a few species reported to cause red tides. Despite their ecological and evolutionary importance, classifying them within Suessiaceae is difficult due to the limitations of the existing molecular markers-the highly conserved small subunit ribosomal gene (SSU rDNA) and the presence of two indel regions of sequence fragments of the large subunit ribosomal gene (LSU rDNA)-resulting in poorly resolved phylogenetic relationships.

Phylogenomic tree reconstruction has recently become a routine and critical task to elucidate the evolutionary relationships among bacterial species. The most widely used method utilizes the concatenated core genes, universally present in a single-copy throughout the bacterial domain. In our previous study, a bioinformatics pipeline termed Up-to-date Bacterial Core Genes (UBCG) was developed with a set of bacterial core genes selected from 1,429 species covering 28 phyla.

Perovskite photovoltaics (PePVs) tend to suffer from a high density of defects that restrict the device in terms of performances and stability. Therefore, defect passivation and film-quality improvement of perovskite active layers are crucial for high-performance PePVs. In this work, 2-chloroethyl acrylate (CEA) with C═O and -Cl groups in CsFAMAPb (IBr) precursor solutions is introduced as a novel bifunctional additive to act as both a defect passivator and perovskite-growth controller.

PCBM is commonly used in perovskite solar cells (PSC) as the electron transport material (ETM). However, PCBM film has various disadvantages, such as its low coverage or the many pinholes that appear due to its aggregation behavior. These faults may lead to undesirable direct contact between the metal cathode and perovskite film, which could result in charge recombination at the perovskite/metal interface.

Solution-processable graphenes (represented by reduced graphene oxides, rGOs) have shown promising abilities as HTLs in perovskite solar cells (PeSCs). However, there has been no attempt to systematically tailor the characteristics of rGOs to the specifications of PeSCs. Furthermore, the applications of rGO HTLs have been limited to the spin-coating system, which is incompatible with roll-to-roll manufacturing.
