Why Amorphous

There are several different types of solar technologies on the market. When determining which technology is best suited to a particular application, consider the attributes that PowerFilm's amorphous Silicon offers:

Lightweight

  • The thin film nature of amorphous silicon make it incredibly light and adaptable to different surfaces as a simple/cost effective installation
  • No requirements for glass or rigid framing
  • Critical in portable applications

Flexible

  • Thin film solar panels are incredibly flexible due to PowerFilm’s unique manufacturing process
  • Allow numerous configurations and applications for solar material
  • See product videos, photos, samples

Light Sensitivity

  • Amorphous Si collects more energy in lower light situations than other technologies
  • Specific PowerFilm material will work in indoor light down to 200 lux
  • Outperforms crystalline and other thin film technologies in many real-world environments collecting energy in cloudy, shady, hazy environments where crystalline panels will not

Durable

  • Monolithic construction makes panels very resilient to damage
  • Damage to individual area shuts down the damaged area not the entire solar panel producing power after being punctured or scratched
  • Critical in potentially high-stress environments or applications
  • See video of panel getting shot here

Temperature Resistant

  • All solar material has temperature coefficient. And, while all panels become less efficient as they get hotter, Amorphous Si is less sensitive to high temperatures than crystalline (0.19% v 0.50% degradation per degree C over 25C)
  • Amorphous Si will perform closer to specifications in high-temperature applications and environments
  • Overall performance through a normal day of outdoor exposure will be greater than crystalline per rated watt

  

Revolutionary Package of Proprietary Solar Technologies

Low Cost Manufacturing and Installation

 

Roll-To-Roll Manufacturing

Roll-to-roll manufacturing significantly reduces manufacturing costs. Our company was the first and remains the only company in the world that manufactures and sells monolithically-integrated solar panels on plastic using a true roll-to-roll manufacturing process.

Polymer Substrate

Flexible yet durable polyimide substrate results in enhanced flexibility, paper thinness and lighter weight. The substrate is as thin as 1 mil (0.025mm) thick.

Thin Film Amorphous Silicon

Amorphous silicon is the absorber layer in the solar panels. The amount of silicon used in PowerFilm® solar panels is as low as 1 percent of the amount used in traditional solar panels. PowerFilm has a strong environmental profile and is cadmium free. Single and tandem junction devices are manufactured. Finished panels are encapsulated in materials appropriate for the application environment.

Manufactured 13 inches wide, up to 2,400 feet long.

Monolithic Integration

Monolithic integration is the automatic built-in-connection of individual solar cells. Monolithic integration reduces manufacturing costs (eliminates expensive labor for manual connection) and increases durability (eliminates stress-prone manual connections of individual solar cells).

Product and Building Integration Technology

PowerFilm® Solar also has developed low-cost technology to integrate the solar panels with products and building materials.

Encapsulation

To optimize the tradeoffs between product functionality, lifetime and cost, the core solar panels are encapsulated in a variety of materials to meet the requirements of diverse applications and use environments.

Backing Materials

The solar panels can be combined with several backing materials, including fabric, metal and fiberglass.

Finally, it all ends on a roll.
