Selective Laser Doping From Boron Silicate Glass

Laser doping for selective emitter solar cells

Selective emitter solar cells were fabricated with a reduced number of technological steps. Laser doping is often discussed in relation to silicon photovoltaic cell efficiency enhancement. In this paper, we present results of the development of a selective emitter structure for multicrystalline silicon solar cells suitable for industrial mass production. A pulsed laser is used to obtain highly ...

Pressure-induced nano-crystallization of silicate garnets from glass

Transparent ceramics are important for scientific and industrial applications because of the superior optical and mechanical properties. It has been suggested that optical transparency and mechanical strength are substantially enhanced if transparent ceramics with nano-crystals are available. However, synthesis of the highly transparent nano-crystalline ceramics has been difficult using convent...

Selecting boron fullerenes by cage-doping mechanisms.

So far, no boron fullerenes were synthesized: more compact sp(3)-bonded clusters are energetically preferred. To circumvent this, metallic clusters have been suggested by Pochet et al. [Phys. Rev. B 83, 081403(R) (2011)] as "seeds" for a possible synthesis which would topologically protect the sp(2) sector of the configuration space. In this paper, we identify a basic pentagonal unit which allo...

Selective Laser Sintering of 13-93 Bioactive Glass

Bioactive glasses are more promising than biopolymers in fabricating scaffolds for bone tissue repair because they convert to hydroxyapatite, when implanted in vivo. Both direct and indirect selective laser sintering (SLS) methods of 13-93 bioactive glass were considered in this research to study the feasibility of fabricating scaffolds for bone repair applications. Stearic acid was used as the...
