Composition pinning growth for efficient and stable all‐inorganic Pb‐Sn perovskite solar cells

InfoMat, EarlyView.
All‐inorganic Pb‐Sn perovskite solar cells are promising for low‐bandgap photovoltaics, but uneven Pb/Sn composition during film growth can create defects and reduce performance. In this study, composition pinning growth was used to hold the Pb/Sn ratio steady during CsPb0.5Sn0.5I3 crystallization, producing more uniform films and higher‐performing ...

Strain Imaging of GaAs by Stimulated Raman Scattering Microscopy

Journal of Raman Spectroscopy, EarlyView.
Telecom‐wavelength stimulated Raman scattering (SRS) microscopy is developed for high‐throughput, nondestructive characterization of gallium arsenide (GaAs). By overcoming optical absorption limits of conventional Raman systems, this technique enables precise visualization of LO phonon frequency variations (< 0.2‐cm−1$$ {}^{-1} $$ precision).
