Long-Term Stability of Dye Sensitized Solar Cells for Large Area Power Applications (LOTS-DSC)

This paper discusses about the accelerated ageing tests on large numbers of dye sensitized solar cells show, that to first order a separation between the effects of the stresses visible light soaking, UV-illumination and thermal treatment on long-term stability which can be made. The corresponding mechanisms are of electrochemical, photochemical and pure chemical nature respectively. It was found that visible light soaking alone is not a dominant stress factor. A dramatic improvement in UV-stability has been reached by using MgI2 as additive to the electrolyte.
