? 2022 Elsevier B.V.Organic solar cells (OSCs) have attracted great interest in recent years owing to such features as low cost, light weight, and flexibility. The top electrodes of OSCs are generally fabricated by vapor deposition on organic layers. Recently, electrode lamination has emerged as a cost-effective process for the fabrication of top electrodes of OSCs because it does not damage organic thin layers. However, problems abound, including the low short-circuit current density (JSC) and the poor device durability of the resulting OSCs, which are due to the weak contact between the laminated electrode films and the organic layers. Herein we report an electrode sticker that can be firmly attached to an organic layer by thermocompression to realize electrode sticker-laminated OSCs with good JSC and device durability. The electrode sticker-laminated OSCs showed high JSC that approached that of electrode-sublimated OSCs, and their PCE values remained unchanged and were 98% of the maximum value after continuous photo-irradiation for 100 h under ambient conditions. The electrode sticker can be used to fabricate low-cost OSCs with good performance and durability for practical applications.
