非晶硅太阳能电池在暴露于阳光的最初几周内通常会表现出转换效率的下降。这种退化与亚稳态缺陷中心有关，亚稳态缺陷中心影响氢化非晶硅的许多特性。本文讨论了这些亚稳中心的模型，该模型基于这样的假设：空穴可以被捕获在微孔附近，并且可以诱导氢在微孔内表面上的运动。
Amorphous-silicon solar cells generally exhibit a degradation of conversion efficiency in the first few weeks of exposure to sun light. This degradation is associated with metastable defect centers that influence many of the properties of hydrogenated amorphous-silicon. This paper discusses a model for these metastable centers that is based on the assumption that holes can be trapped near microvoids and can induce the motion of hydrogen on the internal surfaces of the microvoids.
