Method for Improving the Efficiency of Flexible Organic Solar Cells

A method for improving the efficiency of a flexible organic solar cell, comprising:

• providing a conductive film-coated flexible substrate;
• forming a hole blocking layer on said flexible substrate by atomic layer deposition;
• forming an active layer on said hole blocking layer;
• forming a hole selective layer on said active layer;
• and
• forming a metal electrode on said hole selective layer.
