摘要
A method for determining the susceptibility of solar cell coverglass assemblies to degrade wherein the solar cell assembly contains coated or uncoated coverglass, the method comprises exposing the solar cell coverglass assembly with a pulsing laser having an energy per unit area per pulse which distinguishes by laser damage between coverglass assemblies that have an anomalously high propensity to darken under solar exposure and those that only have a normal, nominal propensity to darken; and, characterizing the propensity of the coverglass assemblies to darken. The process results in an improvement of the long-term power output of solar cells by maintaining optical transparency and reducing temperature increases arising from increased solar absorption in darkened coverglass assemblies.
