“…Top-illuminated solar cells have also been fabricated by using a solution-processed top electrode. Silver nanowires 33 and high conductivity PEDOT:PSS 34,35 have been used as the top electrode. PEDOT:PSS can also be combined with inkjet-printed silver grids to improve the conductivity and the charge collection with a moderate transmittance decrease.…”

We report indium tin oxide-free top-emitting organic light-emitting diodes (OLEDs) with solution-processed organic layers. The two electrodes are made of evaporated silver, creating a Fabry-Perot resonator. The main issue of solution-processed OLEDs is the thickness reproducibility, which greatly influences the top-emitting OLED's performance and color because of the optical resonator. In this work, we combine simulation with experimental results to show the good thickness homogeneity of the spin-coated layers, with a 7% thickness accuracy. Similar efficiencies are obtained for top-and bottomemitting OLEDs based on the same organic materials, 8.1 ± 0.3 cd A À1 and 8.1 ± 0.2 cd A À1 , respectively, with similar Commission Internationale de l'É clairage (CIE) coordinates. This work demonstrates the feasibility to fabricate microcavity top-emitting OLEDs by solution process and the possibility to increase the performance by using a capping layer.

fabricated for application over a large area, and applicability in flexible electronics. [1][2][3][4][5][6] It is possible to design high-performance devices by designing photoactive materials that constitute a bulk heterojunction (BHJ), [7][8][9] device engineering, [10][11][12][13] and a combination of these. [14,15] Therefore, this has attention as an area in which commercialization can occur through the application of flexible, wearable, and portable devices, and building-integrated photovoltaics. [4,[16][17][18][19][20] Recently, different methods such as spin coating, [21][22][23] slotdie coating, [24][25][26] and blade coating, [27,28] are being attempted to develop large-area modules with laboratory-to-industrial applications. Among them, slot-die coating can easily control each layer and the related processing factors, such as discharge rate and speed, thus enabling control of thickness and conformation. Therefore, it is the most appropriate coating method to use to produce devices and modules with large areas. [16,29] Krebs and co-workers fabricated flexible OSC modules using a roll-to-roll (R2R) manufacturing process called "ProcessOne." Their flexible OSC modules with power conversion efficiencies (PCEs) of 2-3% demonstrated an energy payback time (EPBT) of 2.02-1.35 years. [30,31] Using Proces-sOne, the BHJ layer and buffer layer were formed using slot-die coating and the Ag back electrode was formed via screen printing; this resulted in the design of OSC modules with inverted structures, which enabled cost-effective production. [32,33] Several particular challenges need to be considered in the manufacturing of this type of OSC modules using an R2R process; these included thermally treating the film [34,35] and ensuring the thermal stability of the substrate [36] the uniformity of the film morphology, [22][23][24] and the evaporation process of the buffer layer and the electrode. [3,25,26,37] The large-area flexible OSC modules have been reported their efficiencies with various materials and coating methods. In flexible unit-cells with small-area, Peng and co-workers recently reported high PCE of 14.06% introducing ternary heterojunction strategy in active area of 0.04 cm 2 . [38] The flexible OSC module based thermally evaporated top electrode reported relatively higher performances. Zhou and co-workers reported tandem structure with PCE of 6.5% in active area of 10.5 cm 2 , also, Ma and co-workers reported ternary structure with PCE of To ensure laboratory-to-industry transfer of next-generation energy harvesting organic solar cells (OSCs), it is necessary to develop flexible OSC modules that can be produced on a continuous roll-to-roll basis and to apply an allsolution process. In this study, nonfullerene acceptors (NFAs)-based donor polymer, SMD2, is newly designed and synthesized to continuously fabricate high-performance flexible OSC modules. Also, multifunctional hole transport layers (HTLs), WO 3 /HTL solar bilayer HTLs, are developed and applied via an all-solution process called "ProcessOne...

Flexible conductive electrodes are essential components for organic optoelectronic devices (OODs). One of the main challenges in the development of flexible OODs is to achieve an optimal combination of photoelectrical properties, enhanced flexibility and stability in transparent conductive electrodes (TCEs). In this work, highperformance flexible nonfullerene organic solar cells (OSCs) and polymer light-emitting diodes (PLEDs) based on TCEs of silver nanowires (AgNWs) encapsulated with an ultra-thin atomic layer deposited aluminum oxide (Al 2 O 3) have been demonstrated. The hybrid AgNWs/Al 2 O 3 composite electrodes with enhanced thermal, ambient and mechanical stabilities enable an efficient flexible transparent electrode with high transmittance and conductivity, which can synergistically optimize the device performance of nonfullerene OSCs and PLEDs. The maximum power conversion efficiency value of 7.03%, as well as a current efficiency of 7.26 cd A À 1 for flexible OSCs and PLEDs are achieved, respectively. Notably, excellent flexibility, long-term atmospheric and thermal stabilities have been systematically investigated and demonstrated. These results provide a new design platform for the fabrication of high-performance, flexible transparent electrodes, which can be further explored in a wide range of organic optoelectronics field.
