On-demand Lewis base formation strategy boosts efficiency and stability of perovskite solar cells

Color-stable highly luminescent sky-blue perovskite light-emitting diodes

Perovskite light-emitting diodes (PeLEDs) have shown excellent performance in the green and near-infrared spectral regions, with high color purity, efficiency, and brightness. In order to shift the emission wavelength to the blue, compositional engineering (anion mixing) and quantum-confinement engineering (reduced-dimensionality) have been employed. Unfortunately, LED emission profiles shift with increasing driving voltages due to either phase …

On-demand Lewis base formation strategy boosts efficiency and stability of perovskite solar cells

Solar cells based on perovskites, materials with a characteristic crystal structure first unveiled in the mineral calcium titanate (CaTiO3), have emerged as a promising alternative to conventional silicon-based photovoltaics. A key advantage of these materials is that they could yield high power conversion efficiencies (PCEs), yet their production costs could be lower.

Could Perovskite Solar Cells Start Competing with Traditional Silicon Solar Amidst New Tariffs?

When British solar manufacturer Oxford PV shipped the first commercial order of perovskite-silicon solar cells last September, it was touted as a breakthrough in the industry. The news marked a milestone in a 15-year global effort to develop this lightweight, versatile material that could outperform traditional silicon solar cells. But the lack of follow-on shipments since then served as a reminder that this technology wasn’t quite ready for mas…
