Abstract
The present invention discloses a method for improving mass-production yield of large-area organic solar cells for forming the active layer using the roll-to-roll process. The active layer includes low-bandgap high-polymer PTB7, Fullerenes derivative PCBM, and high-boiling-point additives. The addition of the high-boiling-point additives can enhance the efficiency of organic solar cells effectively. In the roll-to-roll process according to the present invention, the drying temperature for the wet film is controlled for controlling the content of additives in the dry film. Thereby, the stability of the overall mass production and the device yield can be both improved.
