摘要
Organic photovoltaics (OPV) has attracted tremendous attention as a promising alternative to silicon wafer-based technologies for building integration. While significant progress has been achieved on the power conversion efficiency of OPV technologies, their field stability is rarely studied. This work investigates the field performance and reliability of a large-area OPV module designed for building integration in tropical Singapore for 4.5 years. The device suffered more than 14% degradation in power at the standard testing conditions from the initial performance, largely due to losses in fill factor (-12% relative). During the monitoring period, it exhibited comparable performance to more conventional silicon PV technologies, with an average specific energy yield of about 4 kWh/kWp/day and an average performance ratio of 0.96. Excellent performance at low light conditions was also observed. However, its field performance was heavily impacted by soiling, which typically led to a 5 to 10% loss in the current output after several months. Further, the device's outdoor performance also showed a three-stage degradation process, including (1) an initial slow degradation in the first 2 years (about -1%/year), (2) a stable period with negligible performance loss from Years 2 to 3.5, and (3) a rapid degradation in the last year (about -5%/year). Organic photovoltaics (OPV) has attracted attention as an alternative to silicon, significantly for its potential in building integration. This work investigates the reliability of a large-area OPV module in the hot and humid tropical climate of Singapore for 4.5 years. The outdoor performance showed an outstanding performance at low irradiance and three-stage degradation process: (1) an initial slow degradation in the first two years, (2) a stable middle period and (3) a rapid degradation after 4 years. image
