The field of polymer PhotoVoltaics (PV)1 has witnessed a fierce development since the first solar cell of this kind was built in the 90’s. Since then the efficiency has increased to almost 11% in a single junction. This progress is a result of a combination of new materials, insight in working principles and new architectures. Material classes will be discussed, also with examples of work at imo-imomec2. Secondly efficiency is critical dependent on achieving an intimately mixed nanomorphology of the donor (conjugated polymer) and acceptor (fullerene) material. This creates a bulk heterojunction which allows for obtaining high performance. The fysico-chemistry behind these material systems starts to be unraveled3 and is essential in understanding what is going on. Recently we started to study also different interlayers which can lead to improvement of more than 15% of the achieved efficiency4. The last critical parameter is lifetime and understanding aging of devices. Some examples of this work will also be presented, specifically related to the study of the behavior of the nanomorphology under thermal stress.
