TECHNOLOGY

Photon Energy Systems has developed a process for making thin (<50u) single crystal silicon photovoltaic devices.

1) All rear contact technology - Increases efficiency by 5-10% over conventional front contact cells.  Improved appearance with all dark front surface.
2) No shading issues - Modules produce partial power even when partially shaded with unique fine grain architecture.
3) Bifacial cells - Power can be collected from the rear side as well as the front - a typical white commercial rooftop can add 15% to the total power output.

4) Voltage flexibilityCells within the submodule can be interconnected in a variety of ways, from all parallel (for standard submodules) to serial parallel combinations for high voltage applications.

5) Shape Flexibility - Microtiles are flexible. Typical submodules contain an EVA front sheet with microtiles impregnated. Flexible submodules are made with mylar front and back sheet.

NEW Silicon Tape Process

Photon Energy Systems has pioneered a completely new concept in photovoltaics. The PES process extracts a 50u thin silicon tape - up to 2 meters long, with widths up to 78mm wide, of monocrystalline silicon.  This tape is then processed into submodules which can range in any size from less than 1 cm2 to 200x200mm.

The cells within the submodule can be interconnected in a variety of ways, from all parallel (for standard submodules) to serial parallel combinations for high voltage applications.

These sub modules are then assembled, laminated and framed into conventional solar panels.
