為了提高有機光伏器件的壽命，通常采用封裝技術來限制太陽能電池在水氧中的暴露程度。盡管聚合物太陽能電池（organic solar cells，OSCs）封裝領域的相關研究已取得系列進展，但文獻中很少研究封裝過程帶來的損傷。以經典的聚-3已基噻吩為給體，[6,6]-苯基-C61-丁酸甲酯為受體，通過將哌嗪作為第三組分提高器件穩定性，以氧化鋅（ZnO）和三氧化鉬（MoO3）為傳輸層材料制備倒置結構OSCs，系統考察大規模卷對卷器件封裝中常用的紫外線（ultraviolet，UV）固化粘合劑對器件光電轉化效率和穩定性的影響。結果表明，隨著輻照時間的延長，UV膠封裝器件的性能（開路電壓、短路電流密度、填充因子和光電轉化效率）呈持續下降趨勢，更換MoO3/Al電極后老化器件性能恢復，證實MoO3/Al界面破壞是器件性能衰減的重要原因。激光束誘導電流成像顯示UV膠封裝出現由邊緣向中心的失效過程。據此，提出如下的降解機理：UV膠中的光引發劑在紫外光照射下會產生強的質子酸，產生的質子酸與MoO3發生反應，阻礙了空穴的有效傳輸，最終使得器件效率大幅度下降。此外，還開發出一種有效的OSCs器件用乙烯醋酸乙烯酯共聚物膜封裝工藝。本研究指出了UV膠固化粘合劑封裝工藝的問題，同時也為提高聚合物太陽能電池的穩定性提供了新策略。

In order to improve the lifetime of organic photovoltaic devices, encapsulation technology is often used to limit the exposure of solar cells to water and oxygen. Despite a series of advances in the encapsulation field of organic solar cells (OSCs), the damage caused by the encapsulation process has rarely been studied in the literature. In this paper, inverted OSCs with high stability were prepared by using classical poly(3-hexylthiophene) as the donor, [6,6]phenyl-C61-butyric acid methyl ester as the acceptor, piperazine that can improve stability of device as the third component, zinc oxide (ZnO) and molybdenum trioxide (MoO3) as the transport layer material. The effect of ultraviolet (UV) curing adhesive commonly used in large-scale roll-to-roll device encapsulating on the photoelectric conversion efficiency and stability is systematically investigated. The results are as follows: the performance (such as open-circuit voltage, short-circuit current density, fill factor, and power conversion efficiency) of UV glue-encapsulated devices shows a continuous decline with the prolongation of the irradiation time. Meanwhile, the performance of the aging devices is restored after replacing the MoO3/Al electrode, which confirms that the MoO3/Al interface corruption is an important reason for the performance attenuation of the device. Laser beam induced current imaging shows a center-to-edge failure process in UV glue-encapsulated device. Based on this, the following degradation mechanism is proposed: the photoinitiator in the UV glue will generate a strong protonic acid under UV light irradiation, and react with MoO3, which hinders the effective transmission of the hole, and ultimately reduces the device efficiency significantly. In addition, an effective ethylene-vinyl acetate copolymer encapsulation process for OSCs devices has also been developed. This study provides a new understanding of the UV glue encapsulation process, and also develops a new strategy for improving the stability of organic solar c
