Cubic silicon carbide as a potential photovoltaic material

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1308673

In this work we present a significant advancement in cubic silicon carbide (3C-SiC) growth in terms of crystal quality and domain size, and indicate its potential use in photovoltaics. To date, the use of 3C-SiC for photovoltaics has not been considered due to the band gap of 2.3 eV being too large ...

Boron-implanted 3C-SiC for intermediate band solar cells

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1308759

Sublimation-grown 3C-SiC crystals were implanted with 2 atomic percent of boron ions at elevated temperature (400 °C) using multiple energies (100 to 575 keV) with a total dose of 8.5×1016 atoms/cm2. The samples were then annealed at 1400, 1500 and 1600 °C for 1h at each temperature. The buried boro...

Solubility of transition metal interstitials in proton conducting BaZrO3 and similar perovskite oxides

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1356180

The defect chemistry of foreign transition metals in perovskite oxides was investigated by first-principles calculations with focus on Ni and Zn in Y-doped BaZrO3. Additional transition metals (Cu, Fe, Pd, Pt, and Ag) and perovskites (SrZrO3 and SrTiO3) were considered for comparison. The octahedral...

Nano Improves Thermoelectric Performance

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1277301

The rule of thumb for improving the performance of thermoelectric materials is to reduce the thermal conduction, which attributes to electron transport and phonon transport. Phonons are characterized by different wavelength, Short wavelength phonons are scattered by impurity atoms in alloyed matels,...

An in situ XPS study of growth of ITO on amorphous hydrogenated Si: Initial stages of heterojunction formation upon processing of ITO/a-Si:H based solar cell structures

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1238895

In this work we studied the interface growth upon deposition of indium-tin oxide (ITO) on amorphous hydrogenated Si (a-Si:H)/crystalline Si (c-Si) structures. The analysis methods used were X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS) in combination with in...

Nanostructuring of undoped ZnSb by Cryo-Milling

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1222088

We report the preparation of nanosized ZnSb powder by cryo-milling. The effect of cryo-milling then hot-pressing of undoped ZnSb was investigated and compared with that of room temperature ball-milling and hot-pressing under different temperature conditions. ZnSb is a semiconductor with favorable th...
