This is the experimental setup used to generate femtosecond laser pulses which serve as an ultrafast "flash " for the camera so that very rapid phenomenon can be filmed

Quantum waves at the heart of organic solar cells

12 December 2013

Researchers have been able to tune ‘coherence’ in organic nanostructures due to the surprise discovery of wavelike electrons in organic materials, revealing the key to generating “long-lived charges” in organic solar cells - material that could revolutionise solar energy.
