摘要: Absorption spectra of two dilution series microcrystalline solar cells deposited by VHF-PECVD were measured FTPS. The composed pin and nip cells, with i-layers ranging from highly crystalline to mainly amorphous. This paper evaluates stability the when exposed white light (AM 1.5-like spectrum). Defect-related absorption is minimum for medium crystallinity (deposited in transition region); but increased theses a factor 2 4 under light-soaking. It still remains lower than that which show very little degradation. Variation electrical parameters also investigated as function soaking annealing steps. Cells approximately 10% reversible relative efficiency loss after 1000 hours soaking.
