CIGS Solar Cell  Equipment Overview
 
CIGS thin film can dramatically reduce the cost of manufacturing solar cell with a high production yield. Started from 2004, Dalux has been focusing on research and manufacturing of the completed TURN-KEY system for CdS treatment, module plant production line and related products of CIGS solar cells equipment.
 


DALUX Perfornmence
  • 2005          Delivered over two digits of Dalux RTR-CdS Coater system worldwide, majorly in USA.
  • 2006          Delivered 3 lines of CIGS on Glass(CBD & KCN)
  • 2009          One full line wastewater treatment system started running in a CIGS factory 
  • 2010          Around 200MW/a world wide of CIGS-PV produced via Dalux System                   
 
 
Typical CIGS Structure

 
Our Technology
  • Before conducting the sputtering, substrate cleaning process can decrease the contact angle and ensure the quality of Mo layer.
  • Through KCN micro-etching before the deposition of CdS thin film, it can decrease the roughness of CIGS surface and reduce the pin hole which may produce during the later CBD process.
  • DALUX equipment, CBD Coater, applies the technology of Chemical Bath Deposition (CBD) to coat nano thin films on the substrates of glass and foil.
  • During the CBD process, the CdS thickness and uniformity can be controlled by adjusting the distribution of flow rate, density and temperature.
