Interlayer for Modified Cathode in Highly Efficient Inverted ITO-Free Organic Solar Cells

摘要

Promising to generate electricity with costs equivalent to the conventional fuel, organic solar cells are now getting closer to commercial application with power conversion efficiencies (PCEs) over 8℅. However, current state of the art organic solar cells are often constructed on substrates coated with indium tin oxide (ITO) acting as hole-collecting anode, which increases the energy and production cost of organic solar cells considerably. Therefore, replacement of ITO on glass by highly conductive, transparent and inexpensive materials is of the utmost importance for the purpose of commercializing organic solar cells.
