The global quest for reliable sources of energy has led to the development of Organic solar cells (OSCs)/ Organic photovoltaics (OPVs). Over the past few years, they have shown great potentials and use as low cost devices for conversion of solar energy. OSCs are designed from different interface layers from different materials which form a major determinant for their energy conversion efficiency. The recent development in the modifications in design and engineering of these interface materials have shown increased power conversion efficiency (PCE%) of Organic photovoltaics. Interface materials are conductors, semiconductors or non-conductors which provide selective contact for carriers, determine polarity and acts as protective layers. This review discusses different materials which are used as interface materials as well as their structure and engineering.
