Organic and hybrid organic-inorganic photovoltaics: from understanding key loss mechanisms to developing new approaches.


James W. Ryan

ICYS-GREEN Researcher


Organic and hybrid organic-inorganic solar cells offer a green route to generating electricity based on earth-abundant materials that are compatible with low-cost solution-based fabrication methods.  In this talk, I will present results on small molecule organic solar cells and hybrid quantum dot / fullerene solar cells, focusing on both device photophysics and the importance of controlling morphology.1-4 I shall also discuss a big issue in organic solar cells and how to overcome it – replacing PCBM without losing photocurrent.5 I will then provide a brief background on organic-inorganic perovskite solar cells and explain how I am contributing to this exciting research field at NIMS.
