报告人简介
Dr. Seyed Mohammad Fattahi is an Assistant Professor of Geotechnical Engineering in the Department of Civil and Environmental Engineering at Amirkabir University of Technology, Tehran, Iran, where he also serves as Head of the Soil Mechanics Laboratory. His research focuses on environmental geotechnics, wind-erosion control, sustainable soil stabilization, alkali-activated materials, and the durability of engineered surfaces under environmental stresses. His work particularly explores the use of waste-derived binders for soil stabilization and erosion and scour mitigation. During his current research visit at Lanzhou University, he is investigating the abrasion and soiling of photovoltaic front glass and coatings caused by windblown sand, with an emphasis on dose-based degradation relationships, optical performance loss, surface damage, and durability assessment.
报告摘要
This presentation introduces my proposed research on the degradation of photovoltaic (PV) front glass and functional coatings under windblown-sand exposure. The study develops a dose-to-degradation framework that relates sand impact dose to optical degradation, surface damage, and power loss. Controlled nozzle and wind-tunnel experiments will be conducted to investigate the effects of impact velocity, angle, particle characteristics, and cumulative exposure. Surface morphology, optical properties, and soiling behavior will be systematically characterized to establish quantitative degradation models. The proposed framework aims to provide a physically meaningful approach for accelerated testing, lifetime prediction, and the evaluation of advanced PV glass and coating technologies for desert environments.
