Sunsonix provides substrate cleaning solutions to the photovoltaic and related industries. Our “Creative Cleaning” technologies provide an environmentally safe process for removal of trace metal contaminants from crystalline silicon solar cells to improve efficiency and reduce degradation.

Sunsonix developed SX-E™ to increase the overall solar efficiency of crystalline silicon solar cells by targeted removal of transition metals from wafer surfaces. Metallic impurities are detrimental to solar cell efficiency due to their ability to cause recombination of charge carriers on the surface and the bulk of the solar cell, reducing the power generating capacity of the cell.

Sunsonix has formulated a cleaning technology with an unparalleled ability to work in concert with existing process sequences, both acidic and alkaline, to aid the removal of surface bound transition metals without damage to the underlying silicon semiconductor. The SX-E solution is non-toxic and biodegradable, features consistent with our mission to develop environmentally friendly cleaning solutions.

SX-E Dramatically Improves Solar Cell Performance

  • Improves Wafer and Cell Purity: Proprietary chemistries and processes remove surface trace contaminants, including: copper, nickel, iron, chrome and other metals that cause cell efficiency loss
  • Increases Solar Cell Efficiency and Energy Yield: Application results in absolute efficiency improvement of typical 0.3%
  • Reduces Cell Variability and Binning Loss
  • Lowers Manufacturing Cost-per-Watt
  • Seamless “drop-in” integration with your existing equipment and processes during all aqueous cleaning steps used in wafer and cell manufacturing

Sunsonix provides substrate cleaning solutions to the photovoltaic and related industries. Our “Creative Cleaning” technologies provide an environmentally safe process for removal of trace metal contaminants from crystalline silicon solar cells to improve efficiency and reduce degradation.

Sunsonix developed Struktur-FX™ to improve anisotropy of the etch or texturing solution. Its additives have been formulated to either enhance the IPA chemistry or eliminate IPA altogether.

Sunsonix has formulated a texturing technology with an unparalleled ability to work in concert with existing alkaline process sequences, and also aids the removal of surface bound transition metals without damage to the underlying silicon semiconductor. The Struktur-FX™ solution is non-toxic and biodegradable, features consistent with our mission to develop environmentally friendly chemistries.
