Less shading

CallGrede_A.jpg

Higher efficiency

Narrow line width - lowers light shading

Improved series resistance due to:

  • High finger aspect ratio (line conductivity)

  • Low finger spacing

  • Robust contact resistance

  • Highly uniform fingers

Improved light capture by:

  • Controlled finger face angle enabling light reflectance to wafer

Lower cost

Ultra-narrow finger width

Super-fine fingers - as low as 5 microns width

Exceptional high aspect ratio - as high as 3:1

Superior finger uniformity

Simple process

Same metallization chemistry as current silver pastes

Significant reduction of silver consumption

Low capital investment

Lumet CAPEX is 80% less than screen printing

Significantly lower OPEX and CAPEX
