“…108,110 The PCE of OPVs, whose active layer consists of polymer and fullerene, is limited due to the low the mobility of the charge carrier relative to the short diffusion length of the exciton. 111 These limitations, along with the advantages of non-fullerene (NF) such as good solubility (essential for large-scale production), process in halogen-free (less toxic) solvents, 75,112 and good thermal stability 72,113 have stimulated research on NF acceptors, [114][115][116] leading to the rapid improvement of PCE produced by NF acceptors. 43,117 OPVs based on NF acceptors achieved PCEs of 11.54%, 118 12.1%, 119 13.1%, 120 14%, 121 and 17.3%.…”

Summary The objective of this article is to identify how organic photovoltaic cells have been addressed in scientific studies published until 2022. To this end, a literature review was conducted, which involved the search for articles through the Advanced Search tool of the Periodicals portal of the Coordination for the Improvement of Higher Education Personnel, as well as the preparation of a Microsoft Excel spreadsheet to assist in the classifying the articles, followed by a structured analysis of the structure, operating principle, materials, performance parameters, stability/life span/degradation, challenges, opportunities, and applications of organic photovoltaic cells. The results of this research point out that organic photovoltaic devices are formed by electrodes (anode, such as indium‐tin oxide, silver nanowires, carbon nanotubes and graphene and cathode, such as calcium, barium, or aluminum), hole transport layers (PEDOT:PSS), and electrons (ZnO or the TiO2), as well as by the active layer (donor, such as P3HT or PTB7, and acceptor, such as C60 and C70 fullerenes and their PCBM derivatives, as well as non‐fulerene acceptors). We further identify that the working principle of organic photovoltaic cells consists in the generation of photocurrent from the absorption of a photon that results in an exciton, this in turn diffuses to the donor–acceptor interface, and disassociates into free carriers, which carry collected charges to the electrodes. We find that organic photovoltaic cells are simple to manufacture, less expensive, more flexible, lightweight, and that the development of these devices has advanced in recent years. However, for practical relevance, some challenges need to be overcome, including power conversion efficiency, stability, degradation, lifetime, as well as fabrication of large areas through roll‐to‐roll methods.

The organic photovoltaic cell (OPV) is composed of multiple layers, and some printing and coating techniques are more suitable than others for a certain type of layer. This paper aims to characterize and compare the most relevant coating and printing techniques that can be used in the manufacture of OPVs. Extensive bibliographic research was carried out on articles published from 1998 to 2020 to identify various aspects OPV, such as the principle of operation, advantages, disadvantages, and which layers can be printed by each technique. The results show that the most used method for the processing of OPVs is spin-coating. In the studies found, rotation was used to coat the active layer, the electron transport layer, and the hole transport layer. The techniques of pad printing, casting, and meniscus are considered useful in the processing of the active layer. Regarding the deposition of the active layer, hole transport layer, electron transport layer, and anode, the rotogravure, crack matrix, spraying, and brushing techniques were satisfactory. Flexography has been used to form the active layer, electron transport layer, and anode. Screen printing, inkjet printing, and knife/blade coating were used in the processing of the active layer, hole transport layer, electron transport layer, anode, and cathode. All the double slot die coating, curtain coating, and slide coating allows simultaneous processing of multiple layers. Techniques compatible with roll-to-roll processing are more likely to be at the center of OPVs in the future, thus making solar photovoltaic technology more competitive.

“…The ITO substrates were ultra‐sonicated twice for 10 min in deionized water followed by acetone and then isopropyl alcohol. A filtered ZnO precursor solution was spun cast onto cleaned ITO substrates and then baked in an oven at 200 °C for 20 min . By this way, a ZnO film of 40 nm was obtained on the ITO substrate.…”

SUMMARYWe investigated the role of pentacene in inverted polymer solar cells based on the blends of poly(3-hexylthiophene) (P3HT), (6,6)-phenyl C 61 -butyric acid methyl ester (PCBM), and pentacene. The performance of organic solar cells with pentacene improved in terms of power conversion efficiency (PCE), thermal stability, and lifetime in the ambient air. The pentacene in the P3HT:PCBM blends modified the crystallization of P3HT and PCBM. The donor-acceptor interface of devices with pentacene was found to be more stable than that without pentacene in the active layer, which was characterized by optical microscopy, atomic force microscopy and ultraviolet-visible absorption spectra. The PCE of pentacene based as-fabricated device was 4.3%, and the PCE of non-encapsulated pentacene device reduced just by about 25% after 4 months.
