K-Space Associates, Inc.
KSA BandiT PV
K-SPACE manufactures state-of-the-art in-situ, real-time thin-film deposition monitoring tools, and has over 20 years of experience in the thin-film metrology field. Today’s solar power generation industry is quickly evolving with a new breed of compound semiconductor materials leading the charge.
These new, thin-film based materials have already surpassed performance requirements needed for global deployment.
However, mass production and yield problems have limited broad commercialization of these promising thin-film PV materials.
that monitoring methodologies be implemented for higher conversion efficiency and reduced manufacturing costs.
This includes implementing in-line metrology tools that monitor the performance metrics of thin-film PV materials being produced so that the manufacturing process variables can be controlled and optimized in real-time.
k-Space has directly addressed this important in-line metrology need with our kSA BandiT PV system.
kSA BandiT PV spectrally analyzes diffusely reflected light via solid state electronics to enable measurements over a wide spectral range. Modular designs and flexible geometries allow for rapid measurement at multiple locations across either glass panel or flexible substrate processing lines.
storage spool on overlapping windings and can therefore damage itself. The innovative DWMS design separates the spool into a supplier (storage part and a working part.
On the working part the wire is wound in non-overlapping windings with a minimal pitch. This completely eliminates wire to wire contact and keeps the wire sharp.
The wire winding system of the diamond wire saws is enhanced by dividing the spools on both sides of the wire web into a supplier (storage and a working part.
Meyer Burger Technology Ltd
Diamond Wire Management System (DWMS)
DIAMOND WIRE MANAGEMENT SYSTEM (DWMS) is an enhanced wire winding system uniquely designed and available for Meyer Burger diamond wire saws.
The DWMS is marketed under the name of DW288 as an integrated option of the successful DW288 platform for mono and multi silicone wafering in the PV industry.
A key factor in producing the highest efficiency cells at the lowest cost will be the successful deployment of automated high-volume production with tight process control. To achieve this goal, it is essential
During cutting the wire is wound and unwound on spools on each side of the wire web respectively. Without DWMS the aggressive wire is wound directly onto the
Before starting the cutting/pilgrim mode fresh diamond wire is transferred from the storage part via the wire web onto the working part of the spool (on the wire supplying side of the web.
During the wafering process itself the wire is wound back and forth in non- overlapping windings without wire to wire contact.
The wire management systems of all wire saw suppliers are direct derivatives of wire management systems for slurry based cutting. Wires for slurry based systems are non-aggressive bare wires.
Such wires can be wound and unwound onto conventional spools in overlapping windings with no harm occurring to the wire itself.
