Growth of Crystalline Silicon for Solar Cells: Czochralski Si,cts and impurities, which are harmful for the performances of solar cells. Therefore, the CZ silicon crystal growth aims at the achievements of defect-free single crystals for advanced solar cell wafers. Meanwhile, the low cost of CZ silicon crystal growth must be paid attention. Therefore, it is ne

Growth of Crystalline Silicon for Solar Cells: Noncontact Crucible Method, diameter and volume using the cast furnace and solar cells with high yield of high conversion efficiency. Several novel characteristics of this method are explained on the view point of the existence of a large low-temperature region in a Si melt which is the key point to realize its enclosing pote

Wafer Processing, primarily driven by the need to reduce cost. The dominant wafering method is multi-wire sawing with a straight steel wire and an abrasive slurry consisting of polyethylene glycols (PEG) and SiC powders (loose abrasive sawing). Substantial cost reductions are possible with structured steel wires or

Wafer Cleaning, Etching, and Texturization, bases resulting in very different etch rates. Underlying chemistry are used for all three applications. Typical cleaning mixtures such as RCA-SC1 and RCA-SC2, SPM and dHF, are introduced with their respective properties, as well as acidic etching systems like hydrofluoric acid/nitric acid (HF/HNO.)

Oxygen Impurity in Crystalline Silicon,during crystal growth. Subsequent thermal treatment during solar cell manufacturing leads to its precipitation which degrades the lifetime of minority carriers in solar cell material and also the solar cell efficiency. Oxide precipitate nuclei are formed already during crystal cooling. A special for

Metal Impurities and Gettering in Crystalline Silicon,ell performance is well documented. This necessitates a study of transition metal properties in Si and their interaction with point and extended defects. Such studies will form the basis for the development of procedures on suppressing the detrimental effects of transition metals. This chapter brief
