METHOD OF CONTROLLING STRUCTURAL QUALITY OF THIN FILMS FOR LIGHT-ABSORBING SOLAR CELL LAYERS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC H01L31/00 H01S4/00 

Abstract RU 2631237 C2

FIELD: physics.

SUBSTANCE: method of controlling the structural quality of thin films for light-absorbing solar cell layers is that the radiation of films is recorded under pulsed laser excitation. The excitation level is set in the range of 10-200 kW/cm2 for the appearance of stimulated emission with the spectrum half-width of Δλ~10 nm, and the intensities and half-widths of the stimulated emission spectra are compared to determine the relative structural quality of the films.

EFFECT: simplification of controlling the structural quality of thin films for light-absorbing solar cell layers.
