Transparent Conductive Electrodes: Figure of Merit Revisited for Photovoltaics — •Harald Hoppe — Center for Energy and Environmental Chemistry Jena (CEEC Jena), Friedrich Schiller University Jena, Philosophenweg 7a, 07743 Jena, Germany — Laboratory of Organic and Macromolecular Chemistry (IOMC), Friedrich Schiller University Jena, Humboldtstrasse 10, 07743 Jena, Germany

Figure of Merits (FOMs) are meant to provide a simple means for assessing the suitability of a certain material for or compartments within devices in general. In case of photovoltaic devices, the role of the transparent conductive electrode is to allow as much as possible light to enter into the device as well as to enable current flow out of the device. Over the last 5 decades a number of FOMs were introduced based on several approaches. Here we present a rather novel, yet implicit approach for an FOM, which is highly suitable for photovoltaics, allowing to assess the potential photovoltaic performance quantitatively.
