“…Thus, the V oc of tandem OSCs is estimated by summing the V oc s of individual subcells, while the overall J sc is determined by the subcell with the smaller current. Ideally, ICLs should have good vertical conductivity to reduce electrical losses, high transmittance over the whole solar spectrum to minimize light absorption, appropriate energetic to facilitate charge recombination, full coverage to avoid subcell intermixing, and low surface roughness to avoid interrupting the deposition of adjacent subcells 22, 275. Therefore, sufficient material design and property control of ICLs is critical for tandem OSCs 276, 277, 278.…”

“…Since the pioneer works in OPVs,16, 17, 18 rapidly increasing PCEs of OSCs are benefited from the developments of new donor/acceptor materials in the active layer and from the innovations of the device structure and geometry 19, 20, 21, 22. For example, high PCEs of 9–10% for single‐junction OSCs are achieved by combining [6,6]‐phenyl‐C71‐butyric acid methyl ester (PC 71 BM) as an acceptor with a low‐bandgap polymer, poly({4,8‐bis[(2‐ethylhexyl)oxy]benzo[1,2‐b:4,5‐b′]dithiophene‐2,6‐diyl}{3‐fluoro‐2‐[(2‐ethylhexyl)carbonyl] thieno[3,4‐b]thiophenediyl}) (PTB7) or its derivative PTB7‐Th (poly[4,8‐bis(5‐(2‐ethylhexyl)thiophen‐2‐yl)benzo[1,2‐ b :4,5‐ b ′]dithiophene‐ co ‐3‐fluorothieno[3,4‐ b ]thiophene‐2‐carboxylate]) as a donor in the active layer 23, 24, 25, 26, 27.…”

Organic solar cells (OSCs) have shown great promise as low‐cost photovoltaic devices for solar energy conversion over the past decade. Interfacial engineering provides a powerful strategy to enhance efficiency and stability of OSCs. With the rapid advances of interface layer materials and active layer materials, power conversion efficiencies (PCEs) of both single‐junction and tandem OSCs have exceeded a landmark value of 10%. This review summarizes the latest advances in interfacial layers for single‐junction and tandem OSCs. Electron or hole transporting materials, including metal oxides, polymers/small‐molecules, metals and metal salts/complexes, carbon‐based materials, organic‐inorganic hybrids/composites, and other emerging materials, are systemically presented as cathode and anode interface layers for high performance OSCs. Meanwhile, incorporating these electron‐transporting and hole‐transporting layer materials as building blocks, a variety of interconnecting layers for conventional or inverted tandem OSCs are comprehensively discussed, along with their functions to bridge the difference between adjacent subcells. By analyzing the structure–property relationships of various interfacial materials, the important design rules for such materials towards high efficiency and stable OSCs are highlighted. Finally, we present a brief summary as well as some perspectives to help researchers understand the current challenges and opportunities in this emerging area of research.

“…After the exciton dissociation into free charge carriers' step, the charges are transported towards the respective electrodes as shown in Figure 4c above. The transportation of charge carriers in organic semiconductors mostly takes place by hopping from one localized state to the next [38]. Separated holes and electrons are dispersed inside the donor and acceptor phases, respectively, after charge transfer occurs at the D/A contact.…”

Meeting our current energy demands requires a reliable and efficient renewable energy source that will bring balance between power generation and energy consumption. Organic photovoltaic cells (OPVs), perovskite solar cells and dye-sensitized solar cells (DSSCs) are among the next-generation technologies that are progressing as potential sustainable renewable energy sources. Since the discoveries of highly conductive organic charge-transfer compounds in the 1950s, organic semiconductors have captured attention. Organic photovoltaic solar cells possess key characteristics ideal for emerging next-generation technologies such as being nontoxic, abundant, an inexpensive nanomaterial with ease of production, including production under ambient conditions. In this review article, we discuss recent methods developed towards improving the stability and average efficiency of nanostructured materials in OPVs aimed at sustainable agriculture and improve land-use efficiency. A comprehensive overview on developing cost-effective and user-friendly organic solar cells to contribute towards improved environmental stability is provided. We also summarize recent advances in the synthetic methods used to produce nanostructured active absorber layers of OPVs with improved efficiencies to supply the energy required towards ending poverty and protecting the planet.

“…Despite their low power conversion efficiencies, OSCs have many advantages such as the processability with solution-based production techniques, low-temperature processing resulting in low-cost producibility, flexibility [14] that enables the OSCs to be applicable on flexible surfaces, roll-to-roll production, with the use of abundant materials [11].…”

Solar energy is one of the most popular energy sources among the other renewable energies. Photovoltaic technology is a clean way to generate electricity from sunlight. Flexible photovoltaics enable portable electronic devices to power at off-grid conditions. Stainless steel mesh fabric was used as a substrate and electrode allowing the light to reach the photoactive layer. The photoactive layer and hole transport layer were deposited by the means of dip-coating like in the textile industry. The metal back electrode was evaporated in a thermal evaporator under vacuum. Promising results were obtained from photovoltaic measurements. About 0.69% power conversion efficiency was obtained from textile-based solar cells in this study. The textile-based metal fabric enables a flexible photovoltaic structure that can be integrated on non-planar surfaces to generate electricity, and also mesh structure allows the light to reach the photoactive layer.
