Highly Efficient Large-area Flexible Organic Photovoltaic Modules: Sustainable Energy Harvesting Under Low-light Conditions |
| 초록 |
This study aims to expand the practical applications of large-area flexible organic photovoltaics, such that they retain their high stability and efficiency even under various weather conditions and external stresses. By developing polyethyleneimine derivative-based CIL and NFA material in OPVs, the PCE and stability decrease rapidly due to an undesirable interaction when these two materials are concomitantly applied. In this study, we designed a novel low-cost metal-mediated cross-linked non-conjugated polymer interfacial layer (c-PEIE) and improved the device performance and stability of flexible OPVs from cell-to-module scale. c-PEIE CIL based flexible OPV cell achieves one of the highest PCE of 16.45% and remarkable photostability. Large-area, flexible OPV module was also fabricated with an excellent PCE of 13.12%.Notably, c-PEIE based OPV devices maintain high output power on cloudy days, which is a particular point of interest to efficiently harvest sunlight energy constantly. |
