Organic solar cells are emerging as promising prospects in the field of solar energy technology due to their low-cost, light-weight and simple roll to roll fabrication properties. A record power conversion efficiency above 19% has already been reported. However, long-term stability is still the main obstacle for commercialization of these devices. In this study, we demonstrate solution processed interlayer encapsulation of organic solar cells using polymer-based barriers to prevent interlayer migration of impurities as well as the ingress of oxygen and moisture.
