Absorption edge of silicon from solar cell spectral response measurements

The optical absorption coefficient of crystalline silicon near the band edge is determined to values as low as 10 −7 cm −1 by sensitive photocurrent measurements on high efficiency silicon solar cells. Structure due to three‐ and four‐phonon assisted absorption processes is observed.

Spectral response measurements of monolithic GaInP…

This measurement artifact is often observed on measuring the spectral response of the Ge bottom cell of GaInP/Ga(In)As/Ge triple-junction cells. The main aspect of the measurement artifact is that the response of another subcell is simultaneously measured, while at the same time the signal of the Ge subcell is too low.
