“…22,34 Sol-gel In-doping of ZnO has been found to reduce the sheet resistance from 42.3 to 35 cm and increased the transparency to visible light, resulting in an increased device efficiency due to an increased photocurrent (Table V). 48 A similar result was obtained by LiF doping of ZnO. This is because Li occupies the interstitial sites and dissociates to give Li + , and the F component occupies substitutional O 2− sites where it accepts one fewer electron than O 2− , both of which lead to an increased carrier concentration (Table V).…”

ZnO and TiO2 are two of the most commonly used n-type metal oxide semiconductors in new generation solar cells due to their abundance, low-cost, and stability. ZnO and TiO2 can be used as active layers, photoanodes, buffer layers, transparent conducting oxides, hole-blocking layers, and intermediate layers. Doping is essential to tailor the materials properties for each application. The dopants used and their impact in solar cells are reviewed. In addition, the advantages, disadvantages, and commercial potential of the various fabrication methods of these oxides are presented.

Organic photovoltaics (OPVs) evolve in an exponential manner in the two key areas of efficiency and stability. The power conversion efficiency (PCE) has in the last decade been increased by almost a factor of ten approaching 10%. A main concern has been the stability that was previously measured in minutes, but can now, in favorable circumstances, exceed many thousands of hours. This astonishing achievement is the subject of this article, which reviews the developments in stability/degradation of OPVs in the last five years. This progress has been gained by several developments, such as inverted device structures of the bulk heterojunction geometry device, which allows for more stable metal electrodes, the choice of more photostable active materials, the introduction of interfacial layers, and roll-to-roll fabrication, which promises fast and cheap production methods while creating its own challenges in terms of stability.

“…The most common issues with these intrinsic oxides are s-shapes in the j-V characteristics due to the poor conductivity, especially when the films are thick and not illuminated with UV light. First examples of organic solar cells employing doped metal oxides as charge transport layer were reported in literature [48,57,58].…”
