The change of the collection efficiency with applied voltage can be explained by the change of the collection length with applied voltage. We have found that a bias light will only influence the collection of photogenerated carriers of a p-i-n solar cell which has very poor fill factor. 由收集长度随外电压的变化可解释电池的收集效率随外电压的变化,只有FF很差的p-i-n电池,偏置光强才影响光生载流子的收集。
Under high bias, electrical properties of all components of the cell can be clearly observed. 在高偏压下,DSC各个组件的电学性质均被清楚观察到。
