摘要

This article presents the capabilities of Raman and photoluminescence (PL) spectroscopy for studying materials for power engineering (the analysis of phase composition, assessment of crystal quality and stability for a wide range of materials, study of the electrodes for metal ion batteries, testing the photostability of photovoltaic devices, etc.). In particular, we demonstrate a possibility to testify material quality by the analysis of spectral width of Raman line or intensity of exciton line in PL spectra, to prove corrosion hardness, to reveal the behavior of electrodes for metal ion batteries by operando Raman analysis under electrochemical polarization, to unveil running photoinduced processes in solar cells by the coupled registration of spectral and photoelectric characteristics and their transformation under illumination.
