“…Low WF alkali earth metals including Mg (−3.7 eV), Ba (−2.7 eV) and Ca (−2.9 eV) and alkali metal compounds such as Cs 2 CO 3 and LiF (WF < 3.0 eV) have been used extensively as the CIL to reduce the WF of the cathode for more efficient electron extraction. However, these pure metals are air‐ and moisture‐sensitive and can be easily oxidized, which significantly decreases the stability of OPV devices . In addition, the requirement for high vacuum and/or thermal deposition of some metal‐based ILs (e.g.…”

In the past two decades, bulk heterojunction organic photovoltaic (OPV) devices have emerged as attractive candidates for solar energy conversion due to their lightweight design and potential for low‐cost, high‐throughput, solution‐phase processability. Interfacial engineering is a proven efficient approach to achieve OPV devices with high power conversion efficiencies. This mini‐review provides an overview of the key structural considerations necessary when undertaking the molecular design of conjugated polyelectrolytes, for application as interfacial layers (ILs). The different roles of ILs are outlined, together with the advantages and disadvantages of competing classes of IL materials. Particular emphasis is placed on the design and synthesis of water‐soluble polythiophene‐based IL materials and the influence of their structural characteristics on their performance as a promising class of IL material. Finally, the challenges and opportunities for polythiophenes as IL materials for OPV devices and other solution‐processed solar cell technologies (e.g. perovskite solar cells) are discussed. © 2017 Society of Chemical Industry

“…They are lightweight, flexible, and suitable for continuous bulk fabrication. As most organic materials degrade with long exposure to solar radiation, [5] The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adts.201900030 [2][3][4] However, the researches in OSCs have to meet the following two very important challenges before their possible commercial use: 1) low PCE, only 12% in comparison with 25% of silicon solar cells; and 2) stability or the problem of degradation with prolonged exposure to sunlight.…”

The power conversion efficiency (PCE) of a hybrid bulk hetero-junction organic solar cell with an active layer of a blend of PBDT TS1 (donor) and PCBM (acceptor) incorporated with copper zinc tin sulfide (CZTS) quantum dots (QDs) and zinc oxide (ZnO) nanowires is simulated. It is found that the incorporation of CZTS-QDs of a single radius (1.5 nm) enhances the PCE from 9.1% to 12.34% and of 13 different radii CZTS-QDs elevates PCE to 14.96%. This enhancement occurs mainly due to the enhancement in absorption that enhances short-circuit current density (J sc ) and fill factor (FF). Finally, a layer of ZnO nanowires is added on top of the glass to reduce the reflection losses and absorption of ultraviolet light in the active layer that causes degradation and reduces the stability of organic solar cells (OSCs). The hybrid structure, thus simulated, has an enhanced PCE of 16.32% and is expected to be relatively more stable. It is expected that the results of this simulation may inspire all researchers interested in the fabrication of highly efficient hybrid OSCs.
