Flex Solar Cells - PowerFilm Rollable Panel 15.4 Volts-300 mA

PowerFilm is manufactured using breakthrough proprietary manufacturing processes. The core process is a true roll-to-roll process. The general process steps are Vacuum Deposition (Back Metal, Amorphous Silicon, Transparent Top Contact), Printing and Laser Scribing, Bus Bar/Lead Attachment, Encapsulation, and Die Cutting. PowerFilm is patterned on a 13 inch wide web on a roll up to 2400 feet long. The proprietary roll-to-roll semiconductor manufacturing process of Iowa Thin Film TechnologiesTM enables lower-cost manufacturing and enhanced product functionality through ease of customization. Overall efficiency is strongly dependent on the module design configuration which determines the percentage of the area which is actually collecting sunlight. You can use 5% as a starting point. We have ongoing research and development programs to continue to improve the efficiency of PowerFilm modules. Note: There are widely varying standards for module efficiency numbers. We encourage you to test actual commercially manufactured modules on a consistent basis.
