The development of ambient-air-processable organic-inorganic halide perovskite solar cells (OIHPSCs) is a challenge necessary for the transfer of laboratory-scale technology to large-scale and low-cost manufacturing of such devices. Different approaches like additives, antisolvents, composition engineering, and different deposition techniques have been employed to improve the morphology of the perovskite films. Additives that can form Lewis acid-base adducts are known to minimize extrinsic impacts that trigger defects in ambient air.

- Incorporating large organic cations enhances the stability of perovskite solar cells, but low electron mobility requires careful alignment of organic sheets for optimal charge transport.
- Additives like methylammonium chloride (MACl) can help achieve this crystal orientation, though the full understanding of their role in nucleation has been lacking.
- By examining the crystallization process and employing 3-fluorobenzylammonium, researchers found a high degree of preferential orientation and moisture-resistant perovskite films, providing insights for developing better additives for more stable perovskite technologies.
Ultraviolet light is essential for disinfection, fluorescence excitation, curing, and medical treatment. An ultraviolet light source with the small footprint and excellent optical characteristics of vertical-cavity surface-emitting lasers (VCSELs) may enable new applications in all these areas. Until now, there have only been a few demonstrations of ultraviolet-emitting VCSELs, mainly optically pumped, and all with low Al-content AlGaN cavities and emission near the bandgap of GaN (360 nm).
