S) and high intensity (-lOAMi.S) illuminations obtained from WACOM solar simulator. The light soaking experiments were done on two f)'Pes of stmctures, namely, pin and p inp in solar cells. The devices were prepared by plasma enhanced chemical vapour deposition (PECVD) technique in a commercial J-clwmber PECVD systems On 10*10 cm2 glass substrate. The effect of various factors such as temperature, i-layer thicknesses, etc., on the degradatiO/I behavior of a-Si:H solar cells were inl'estigated. The paper presents the e.tperimental results obtained from light soaking tests on pin and pilip in samples under these dijJerellt conditionsenDegradation on Hydrogenated AmorphousThesis
