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 have complex power conversion processes. To maneuver around this problem, researchers have developed a method to determine the absolute value of the charge formation efficiency. The secret of their method is the combination of two types of spectroscopy.
