Study on performance degradation and damage modes of thin-film photovoltaic cell subjected to particle impact

Abstract It has been a key issue for photovoltaic (PV) cells to survive under mechanical impacts by tiny dust. In this paper, the performance degradation and the damage behavior of PV cells subjected to massive dust impact are investigated using laser-shock driven particle impact experiments and mec...
