Summary
High-performance flexible indium tin oxide (ITO) films were created using ion plating for perovskite solar cells. This method yields superior conductivity, transparency, and flexibility compared to traditional sputtering techniques.
Area of Science:
- Materials Science
- Renewable Energy
- Thin Film Technology
Background:
- Flexible perovskite solar cells require high-performance transparent conductive electrodes.
- Traditional sputtering methods for indium tin oxide (ITO) films have limitations in achieving desired properties for flexible applications.
Purpose of the Study:
- To develop and evaluate flexible indium tin oxide (ITO) films prepared by in-line type vertical plasma arc ion plating.
- To assess the suitability of these ion-plated ITO films as transparent electrodes for high-performance flexible perovskite solar cells.
Main Methods:
- In-line type vertical plasma arc ion plating was employed for room-temperature deposition of Sn-doped In2O3 (ITO) films.
- Characterization included measurements of sheet resistance, optical transmittance, and outer bending radius.
- Flexible perovskite solar cells were fabricated using the ion-plated ITO electrodes for performance comparison.
Main Results:
- Ion-plated ITO films exhibited a low sheet resistance of 15.75 Ohm/sq and high optical transmittance of 85.88%.
- The films demonstrated excellent flexibility with a small outer bending radius of 5 mm.
- Perovskite solar cells using ion-plated ITO achieved a higher power conversion efficiency of 16.8% compared to sputtered ITO.
Conclusions:
- In-line vertical plasma arc ion plating is a promising technique for fabricating high-performance flexible ITO films.
- The superior crystallinity and adhesion of ion-plated ITO films enhance their suitability for flexible perovskite solar cells.
- Ion-plated ITO films represent a viable alternative to sputtered ITO for advanced flexible electronic applications.

00:52¹H NMR of Conformationally Flexible Molecules: Temporal Resolution
1.3K
At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

The axial and equatorial protons in cyclohexane can be distinguished by performing a variable-temperature NMR experiment. In this process, except for one proton, the remaining eleven protons are replaced by deuterium. The deuterium substitution avoids the possible peak splitting caused by the spin-spin coupling between the adjacent protons. The remaining proton flips between the axial and equatorial positions.

Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

54.5K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.
