  • Shaped Crystals
    The book was intended to be a practical introduction to μ-PD for material scientists (who are often not crystal growers ). … mainly targeted at individuals who want to understand the basics of this crystal growth method and its … the case of highly developed edge - defined film - fed growth (EFG) and/or the Stepanov technique. These chapters are par- ticularly important because they provide direct instructions for readers who wish to reproduce the procedures and the materials studied in their labo- ratories .
  • Recent progress in the photovoltaic manufacturing technology project (PVMaT)
    Springborn Laboratories Mobil Solar Energy Corp.

  • Decade of PV Industry R and D Advances in Silicon Module Manufacturing
    The Ingot/boule/sheet/ribbon size has increased by 122%, and the number of growers has increased by 202%. [2] James Rand, Ralf Jonczyk, “Silicon Solar Cell Manufacturing 10 Years of Volume Growth and Cost Reduction,” 10 Workshop on Crystal line Silicon Solar Cellth Materials and Processes, CO, Aug. 2000. National Renewable Energy Laboratory 1617 Cole Blvd. Funded Si technologies in this project have been Czochralski, cast polycrystalline, edge - defined film - fed growth (EFG) ribbon, string ribbon, and Si-film.
  • Springer Handbook of Crystal Growth
    To achieve this continuous cooperation between a crystal grower and crystal user is necessary. Without good characterization of the crystals grown no progress in crystal growth can be achieved. Soon after this, Gomperz [13.7] used floating dies to control the fiber diameter [an early Stepanov or edge - defined film - fed growth (EFG) process] [13.5]. Since the implantation of the LHPG system at Stan- ford University laboratories , several modifications have been proposed …
  • Bulk Crystal Growth of Electronic Optical and Optoelectronic Materials Complete Document
    Silicon carbide bulk growth has been pursued in both university and industry laboratories addressing both fundamental growth mechanism and practical production issues [6–27]. The latest achievements in the bulk growth of large size SiC crystals by Cree Research and Nippon … The above attractive features have spurred great interest among crystal growers in the [1120] growth direction, also … These include continuous Czochralski growth, and some of the nontraditional growth methods that have been devel- oped for PV that will be discussed in a later section (electromagnetic continuous casting, continuous dendritic web growth, continuous edge - defined , film - fed growth (EFG), etc.).
  • Springer Handbook of Electronic and Photonic Materials
    Crystals were produced up to 20 mm in diameter and with x values of up to 0.6 in the tip regions of some crystals (this has recently been in- creased … … 20 mm diameter in the author’s laboratory [12.42,116]). The entire growth procedure takes several months but gives uni- form material. Czochral- ski growth is still the mainstay of oxide growth, although problems with shape (diameter) control of some oxides (including rare earth vanadates and rutile) necessitate the use of edge - defined film - fed growth (EFG). … granular polysilicon of a free-flowing form and high bulk density enables crystal growers to obtain the …
