ResumoWe observe a significant light-induced increase in open-circuit voltage, Voc, of solar cells whose intrinsic (i) layer consists of an amorphous and microcrystalline mixed phase. The increase depends on the i-layer thickness and light-soaking intensity. An increase of as large as 150 mV or 20% of the original Voc is observed. The original Voc is restored after subsequent thermal annealing. The possible mechanism for the Voc increase is discussed.
