“…Absorption of light radiation by solar cells can be accompanied by heating. Recently, the degradation of GaAs solar cells under continuous laser irradiation was discussed by Lei Qi et al [ 11 ] in terms of thermal-stress distributions. Here, we discussed the degradation caused by defects formed due to redistribution of aluminum and titanium components.…”

This work is dedicated to the description of the degradation of GaAs solar cells under continuous laser irradiation. Constant and strong exposure of the solar cell was performed over two months. Time-dependent electrical characteristics are presented. The structure of the solar cells was studied at the first and last stages of degradation test. The data from Raman spectroscopy, reflectometry, and secondary ion mass spectrometry confirm displacement of titanium and aluminum atoms. X-ray photoelectron spectroscopy showed a slight redistribution of oxygen bonds in the anti-corrosion coating.
