Abstract
Advanced characterisation plays an important role for further improvements of the cost effectiveness ($/Wp) of solar cells. This paper presents an overview of advanced characterisation techniques that are presently being used for the analysis of silicon wafer solar cells, either in the laboratory or in the [...]
PAM-XIAMEN offers InGaAs APD wafers with high performance. InGaAs avalanche photo diodes(InGaAs APD) are highly regarded for its low noise, higher bandwidth, and spectral response extended to 1700 nm. It is available for 1550nm wavelength after optimizing and very suitable for use in eye-safe laser ranging [...]
