摘要：
We observe a significant light-induced increase in open-circuit voltage, V-oc, 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 V-oc is observed. The original V-oc is restored after subsequent thermal annealing. The possible mechanism for the V-oc increase is discussed. (C) 2001 American Institute of Physics.
