XsunX CIGS solar cell device surpasses 14% conversion efficiency

XsunX announced that its CIGS thin film solar cell technology, associated with the use of thermal co-evaporation techniques to produce the CIGS solar absorbing layer, acheived 14% efficiency, then 15.09% a week later. (Updated November 9, 2010)

(October 20, 2010) — XsunX announced that its CIGS thin film solar cell technology, associated with the use of thermal co-evaporation techniques to produce the CIGS solar absorbing layer, acheived 14% efficiency. Then, a week later, XsunX saw efficiency push past 15% to 15.09%. (Updated November 9, 2010)

XsunX has previously reported initial success with the co-evaporation of the CIGS layer producing films and devices that exhibited excellent film uniformity and high open circuit voltage typical for optimal quality CIGS films. The company successfully fabricated cells based on its CIGSolar technology that surpass 14% conversion efficiency.

“We have been working hard to improve efficiencies and the properties of the CIGS absorber since adding co-evaporation capability to our process development,” said president and COO Joseph Grimes.

Deposition of the CIGS cell layer was conducted on full-size 125mm-square substrates. Test configurations used to measure efficiency are identical to that used by the National Renewable Energy Laboratory and XsunX test equipment is calibrated to the standards of the National Institute of Standards and Technology (NIST).
