Polymer solar cells (PSCs) are a new type of renewable energy source currently being extensively investigated due to perceived advantages; such as being lightweight, low-cost and because of the unlimited materials resource. The power conversion efficiency of state-of-the-art PSCs has increased dramatically in the past few years, obtained mainly through the development of new electron donor polymers, acceptors, and novel device structures through the use of various electrode interfacial materials. In this short review, recent progress in solution-processed cathode interfacial layers that could significantly improve device performances is summarized and highlighted.

“…In inverted devices, where such layers act as a electron transport layer, ZnO has made significant impact as an interlayer [11,18] owing to its direct band gap, high electron mobility, and high transmission over the visible wavelength range [19] . To eliminate high temperatures from the processing nanoparticle based routes have been explored [20,21] however synthesis can be complex and the resultant films may be rough and inhomogeneous [22] .…”

Processing temperature is highlighted as a convenient means of controlling the optical and charge transport properties of solution processed electron transport layers (ETLs) in inverted polymer solar cells. Using the well-studied active layer -poly(3-hexylthiophene-2,5-diyl) (P3HT):indene-C 60 bisadduct (ICBA) -we show the influence of ETL processing temperatures from 25 °C -450 °C, reporting the role of crystallinity, structure, charge transport and Fermi level (E F ) on numerous device performance characteristics. We determine that an exceptionally low temperature processed ETL (110 °C) increases that device power conversion efficiency (PCE) by a factor greater than 50% compared with a high temperature (450 °C) processed ETL. Modulations in device series and shunt resistance, induced by changes in the ETL transport properties are observed in parallel to significant changes in device open circuit voltage attributed to changes on the E F of the ETLs. Our work highlights the importance of interlayer control in multilayer photovoltaic devices and presents a convenient material compatible with future flexible and roll-to-roll processes.

The present review rationalizes the significance of the metal oxide semiconductor (MOS) interfaces in the field of photovoltaics and photocatalysis. This perspective considers the role of interface science in energy harvesting using organic photovoltaics (OPVs) and dye-sensitized solar cells (DSSCs). These interfaces include large surface area junctions between photoelectrodes and dyes, the interlayer grain boundaries within the photoanodes, and the interfaces between photoactive layers and the top and bottom contacts. Controlling the collection and minimizing the trapping of charge carriers at these boundaries is crucial to overall power conversion efficiency of solar cells. Similarly, MOS photocatalysts exhibit strong variations in their photocatalytic activities as a function of band structure and surface states. Here, the MOS interface plays a vital role in the generation of OH radicals, which forms the basis of the photocatalytic processes. The physical chemistry and materials science of these MOS interfaces and their influence on device performance are also discussed.
