Degeneration And Damage Mechanism Of Pseudomorphic Glass Under 170 Kev Proton Irradiation

As the covering layer of flexible solar cells, Pseudomorphic Glass (PMG) needs brilliant optical, mechanical and radiation protection properties to ensure the long-term stable operation of cells. In this paper, the evolution law and mechanism analysis of PMG optical and mechanical properties under 170 keV proton irradiation were studied systematically. The surface morphology and the occurrence of cracks before and after irradiation were observed by OLYMPUS optical microscope and SEM. The degradation characteristics of PMG optical performance were researched by comparing the changes of RTV sheet and PMG transmittance. FT-IR and XPS were used to study the vicissitudes of surface composition and chemical bonds, and based on this, the degradation and crosslinking mechanism of silicon rubber molecular chains after proton irradiation was given. In addition, the stress-strain test was selected to characterize the mechanical properties of PMG.
