PlutoTM Cells

Suntech's Crowning Achievement

More Fingers More Power.
Pluto’s extra fine cell fingers (~30μm), reduce surface
shading and boost sunlight absorption into the cell and give
the product its sleek appearance.

Suntech’s patent-pending PlutoTM technology is the crowning achievement of our R&D team to date. Pluto has the potential
to redefine the landscape of crystalline silicon cell
technologies. Its benefits are numerous—it achieves around
12% higher conversion efficiency and power output than conventional screen-printed PV cells; it works equally well on a variety of forms of silicon including both multi- and
mono-crystalline solar-grade silicon wafers. The higher
efficiency levels help reduce balance of system costs.

Pluto™ Cell Technology Key Features

  • Pluto cells have a sleek appearance due to extra fine cell fingers ~30μm which reduces surface shading
    and boosts sunlight absorption into the cell
  • Pluto monocrystalline cells now undergo Suntech’s proprietary Gallium-F22 doping process, which
    greatly inhibits initial Light Induced Degradation to < 1%.
  • Pluto cells enjoy high shunt resistance (Rsh) which enhances low light performance to generate more
    power on cloudy days.
  • Unique pyramid texturing technology reduces light reflection and helps more sunlight enter from
    oblique & grazing incidences, thus allowing Pluto cells to generate more field power output than conventional
    solar cells
