Researchers at University of Tsukuba and National Institute
for Materials Science use charge formation efficiency to screen materials for
future devices
Organic photovoltaic cells -- a type of solar cell that uses
polymeric materials to capture sunlight -- show tremendous promise as energy
conversion devices, thanks to key attributes such as flexibility and low-cost
production.
But one giant hurdle holding back organic photovoltaic
technologies have been the complexity of their power conversion processes,
which involve separate charge formation and transport processes.
