ABSTRACT

  In this presentation, I will share with you three stories on how to approach high performance solution-processed polymer solar cells and what is the strategy to approach 15% efficiency from single-junction polymer solar cells.

1. By      development of novel 2D conjugated polymer to enhance the hole mobility of      conjugated polymers, we are able to observe over 10 % efficiency from      single-junction polymer solar cells;

2. By      application of magnetic nanoparticles and external magnetic field into      bulk heterojunction polymer solar cells, we are able to observe more than      50 % enhanced efficiency from single junction polymer solar cells;

3. By tuning      the surface energy of the electron extraction layer, we are able to      observe over 7 % efficiency from inverted polymer solar cells with over 1      µm thick active layer, the best efficiency from polymer solar cells with      printable active layer.
