“…To improve the coating quality, uniformity, and morphological control of the active layer, there are several examples of the implementation of in situ annealing [ 84 , 137 , 140 , 141 , 145 , 151 , 152 , 153 ], as well as the use of hot air upon the deposition of the film [ 84 , 137 ]. These methods have allowed for the fabrication of laboratory- [ 139 , 149 ], medium- [ 81 , 140 , 148 , 154 , 155 ], and large-scale [ 16 , 81 , 84 , 137 , 156 ] OPV devices. Though some blade-coated OPVs are prepared under nitrogen [ 143 , 145 , 146 , 147 ] and argon [ 85 ] conditions to allow for the best performance possible, a vast majority fabricate these devices under ambient conditions [ 139 , 140 , 141 , 143 , 144 , 149 , 150 , 153 ].…”

Within recent years, there has been an increased interest towards organic photovoltaics (OPVs), especially with their significant device performance reaching beyond 19% since 2022. With these advances in the device performance of laboratory-scaled OPVs, there has also been more attention directed towards using printing and coating methods that are compatible with large-scale fabrication. Though large-area (>100 cm2) OPVs have reached an efficiency of 15%, this is still behind that of laboratory-scale OPVs. There also needs to be more focus on determining strategies for improving the lifetime of OPVs that are suitable for scalable manufacturing, as well as methods for reducing material and manufacturing costs. In this paper, we compare several printing and coating methods that are employed to fabricate OPVs, with the main focus towards the deposition of the active layer. This includes a comparison of performances at laboratory (<1 cm2), small (1–10 cm2), medium (10–100 cm2), and large (>100 cm2) active area fabrications, encompassing devices that use scalable printing and coating methods for only the active layer, as well as “fully printed/coated” devices. The article also compares the research focus of each of the printing and coating techniques and predicts the general direction that scalable and large-scale OPVs will head towards.

Large areas and simple processing methods are necessary for the commercialization of organic photovoltaics (OPVs). However, the efficiency drop due to the variation in thickness of OPVs limits their large-scale applications. Regioregular polymers with good crystallinity and packing properties that exhibit high charge mobility and extraction ability can help overcome these limitations. In this study, a regioregular polymer named PDBD-2FBT was synthesized. The crystallinity and packing properties of PDBD-2FBT were enhanced by a simple thermal treatment. Using PDBD-2FBT material as a donor and Y6-HU as an acceptor, we fabricated binary blend OPV devices. The devices with optimized active layer thickness achieved a power conversion efficiency (PCE) of 14.14%. A PCE of 13.18% was maintained even in thick-film conditions (400 nm), and thickness tolerance was observed. Based on the thickness tolerance, a 5-line module measuring 36 cm 2 was fabricated via the bar-coating method, and a PCE of approximately 10% was achieved.
