Identification of defects causing performance degradation of high temperature n-type Czochralski silicon bifacial solar cells

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1375936

Four industrial-scale n-type Czochralski silicon crystals were grown with different impurity contents, i.e. metallics, phosphorus and oxygen. Horizontal slices were obtained from the top and middle of the crystals and were characterized in terms of lifetime and both defect and impurity distribution....

Investigation of different cases of dislocation generation during industrial Cz silicon pulling

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1429896

This study aims at better understanding the generation of dislocations causing a structure loss issue during the pulling of Czochralski silicon ingots. Several industrial-scale n-type ingots containing this issue were characterized. The generation and propagation of dislocations were observed in eac...

Influence of Copper Diffusion on Lifetime Degradation in n-type Czochralski Silicon for Solar Cells

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1312559

The impact of copper (Cu) contamination on the minority carrier lifetime degradation of the last solidified fraction of ann-type Czochralski (CZ) silicon ingot was investigated. Lifetime degradation of more than 50% was measured at the top of an as-cut block during the first 2000 h (∼83 days). Depth...

Microstructural characterization of Si wafers processed by multi-wire sawing of hot pressed silicon powder based ingots

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1241534

The purpose of this work is to verify the possibility to process highly doped Si supporting substrates using a 2-step process: (i) sintering of a low-cost Si powder based ingot using hot pressing and a ELKEM Silgrain material as a feedstock; and (ii) wafering of such ingots using multi-wire sawing t...

Enhanced performance in the deteriorated area of multicrystalline silicon wafers by internal gettering

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1240701

The deteriorated area of the multicrystalline silicon (mc-Si) ingots grown by directional solidification, commonly known as the Red Zone, is usually removed before wafering. This area, characterized by poor minority carrier lifetime, is located on the sides, at the top, and the bottom of the mc-Si i...

On the shape of n-type Czochralski silicon top ingots

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1250286

Industrial scale n-type monocrystalline silicon ingots with different crown shape and shouldering area have been grown and characterized in terms of minority carrier lifetime, resistivity and concentration and distribution of interstitial oxygen (Oi), voids and thermal donors (TD). The properties ha...

Investigating the effect of carbon on oxygen behavior in n-type Czochralski silicon for PV application

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1197912

The objective of the current work was to understand the effect of carbon as an impurity in silicon in terms of the formation of as-grown oxygen defects and the subsequent behavior of these defects in n-type Czochralski (Cz) silicon during heat treatment. Three n-type Cz ingots with different carbon ...
