Electrical Characterization of Amorphous Silicon Nitride Passivation Layers for Crystalline Silicon Solar Cells

Helland, Susanne (Master thesis, 2011)

High quality surface passivation is important for the reduction of recombination losses in solar cells. In this work, the passivation properties of amorphous hydrogenated silicon nitride for crystalline silicon solar cells ...

Optical parametric master oscillator and power amplifier for efficient conversion of high-energy pulses with high beam quality

Arisholm, Gunnar; Nordseth, Ørnulf; Rustad, Gunnar (Journal article; Peer reviewed, 2004)

We describe a system for parametric conversion of high-energy, Q-switched laser pulses from 1.064 µm to 2.1 µm in KTiOPO4. High beam quality and efficiency are obtained by use of a two-stage system: An optical parametric ...
